Pinyin, as a basic tool for Chinese learning, has seemingly simple writing rules, but it contains profound linguistic principles and historical background. This paper will explore the writing skills of Pinyin from many angles, reveal the logic and reasons behind it, and help readers better understand and master this important language tool.

First, the origin and development of Pinyin

The origin of Pinyin can be traced back to the early 20th century, when linguists in China began to study how to mark the pronunciation of Chinese with Latin letters in order to simplify the study of Chinese characters and popularize Mandarin. After many discussions and experiments, the "Chinese Pinyin Scheme" was finally published in 1958. This scheme not only considers the phonetic characteristics of Chinese, but also refers to the usage habits of international phonetic symbols, which makes pinyin conform to the pronunciation rules of Chinese and easy to communicate internationally. During the development of Pinyin, it has undergone many revisions and improvements. Each revision is based on a lot of language practice and scientific research, which ensures the scientificity and practicability of Pinyin system.

Second, the collocation rules of initials and finals

In pinyin, there are certain rules for the collocation of initials and finals, which are based on the syllable structure of Chinese. For example, some initials can only be collocated with specific finals, which reflects the pronunciation characteristics of some syllables in Chinese. Knowing these rules can help learners spell Chinese characters more accurately and avoid pronunciation mistakes. The collocation rules of initials and finals are not made at will, but based on the phonological principle of Chinese. For example, the initials of lip sounds (such as B, P, M) are usually matched with open vowels (such as A, O, E), because lip sounds need a large oral space when they are pronounced, and open vowels just meet this condition. The collocation of some initials and finals is also influenced by historical sound changes. For example, some syllables in ancient Chinese have disappeared in modern Chinese, but the collocation rules of these syllables are still retained in Pinyin.

Third, the use and significance of tone symbols

Chinese is a kind of tonal language, and the change of tone can change the meaning of words. Tone symbols in Pinyin (such as ā, á, m 4, à) are used to express different tones. The use of these symbols not only helps to distinguish homophones, but also reflects the richness and complexity of Chinese pronunciation. Mastering the correct use of tone symbols is very important for improving the accuracy of spoken Chinese expression. The use of tone symbols is not arbitrary, but a four-tone system based on Chinese. The four-tone system includes flat tone, rising tone, falling tone and entering tone, and each tone has its own unique pitch and sound length characteristics. Tone symbols in Pinyin represent these tones through different symbol shapes and positions, such as "ˉ" for flat tone, "ˊ "for rising tone," ˇ "for falling tone and" ˋ "for entering tone. The use of these symbols not only helps learners to pronounce correctly, but also reflects the historical evolution and regional differences of Chinese pronunciation.

Fourth, the correspondence between pinyin and Chinese characters

There is a close correspondence between pinyin and Chinese characters. Every Chinese character has its corresponding pinyin, and this correspondence is determined based on the pronunciation of Chinese characters. Understanding this correspondence can help learners remember Chinese characters faster and improve the efficiency of reading and writing. The correspondence between pinyin and Chinese characters is not one-to-one, but many-to-many. For example, the same pinyin can correspond to multiple Chinese characters, such as "ma" can correspond to the words "Ma", "Ma" and "Ma". This many-to-many relationship reflects the existence of homophones in Chinese, and it also increases the difficulty of learning Chinese characters. By mastering the corresponding relationship between pinyin and Chinese characters, learners can better understand the pronunciation rules of Chinese characters, thus improving the learning efficiency of Chinese characters.

Fifth, the application of Pinyin in Chinese teaching

Pinyin plays an important role in Chinese teaching. For beginners, pinyin is the basis of learning Chinese pronunciation. Through pinyin, learners can gradually master the phonetic system of Chinese, and then improve their listening, speaking, reading and writing abilities. The application of pinyin in Chinese teaching is not limited to pronunciation teaching, but also includes vocabulary teaching, grammar teaching and reading teaching. For example, in vocabulary teaching, pinyin can help learners remember the pronunciation of words accurately; In grammar teaching, pinyin can help learners understand the structure of sentences and grammar rules; In reading teaching, pinyin can help learners quickly identify the pronunciation and meaning of new words. The extensive application of Pinyin in Chinese teaching not only improves the efficiency of Chinese teaching, but also enhances learners’ interest and self-confidence.

VI. Internationalization and Standardization of Pinyin

With the increasing status of China in the international arena, as a tool of international communication, the standardization and internationalization of Pinyin are particularly important. The standardization of Pinyin not only contributes to the international spread of Chinese, but also promotes the communication and integration between Chinese and other languages. In the process of the internationalization of Pinyin, it has experienced the formulation and promotion of many international standards. For example, the International Organization for Standardization (ISO) officially adopted Chinese Pinyin as an international standard in 1982, which made Pinyin widely used in international communication. The internationalization of Pinyin also promotes the communication and integration between Chinese and other languages. For example, in English, French, German and other languages, Pinyin is widely used to mark the pronunciation of Chinese words. The internationalization of Pinyin not only improves the international influence of Chinese, but also promotes the communication and integration between Chinese and other languages.

Seven, the relationship between pinyin and dialect.

There are many Chinese dialects, and each dialect has its own unique pronunciation characteristics. As a standardized pronunciation system, how to coordinate pinyin with dialect pronunciation is a problem worth discussing. Understanding the relationship between Pinyin and dialects can help learners better understand the diversity of Chinese and communicate effectively in different dialect areas. The relationship between pinyin and dialect is not antagonistic, but complementary. Pinyin, as a standardized pronunciation system, provides a reference and standard for dialect pronunciation. For example, in Putonghua teaching, Pinyin can help learners master the pronunciation of Putonghua accurately, and at the same time, it can also help learners in dialect areas understand the pronunciation differences between Putonghua and dialects. Pinyin can also be used to mark the pronunciation of dialect words, thus promoting the inheritance and development of dialects.

Eight, pinyin input method and information technology

With the development of information technology, pinyin input method has become one of the main ways to input Chinese characters. The design of pinyin input method not only considers the writing rules of pinyin, but also combines the structure of Chinese characters and the frequency of common words, making the input process more efficient and convenient. The design principle of pinyin input method is based on the corresponding relationship between pinyin and Chinese characters, and the corresponding Chinese characters are retrieved and selected by inputting pinyin. The design of pinyin input method not only considers the writing rules of pinyin, but also combines the structure of Chinese characters and the frequency of common words, making the input process more efficient and convenient. For example, the pinyin input method usually adopts intelligent association and word frequency statistics technology, and automatically recommends the most possible Chinese characters and phrases according to the user’s input habits and the frequency of common words. The wide application of pinyin input method not only improves the efficiency of Chinese character input, but also promotes the application of information technology in Chinese teaching and learning.

Nine, the writing standard and beauty of Pinyin

Pinyin writing requires not only accuracy, but also beauty. The writing standard of pinyin includes the case of letters, the position of tone symbols, and the spacing between letters. Mastering these writing norms can not only improve the recognition of pinyin, but also enhance the aesthetic feeling of writing. The writing standard of pinyin is not made at will, but based on the writing habits of Latin letters and the pronunciation characteristics of Chinese. For example, the tone symbols in pinyin are usually marked above the vowel, because the tone symbols need to be closely combined with the pronunciation of the vowel, so as to accurately represent the tone of Chinese. Pinyin writing also requires that the spacing between letters should be moderate, neither too tight nor too loose, so as to ensure the overall beauty and readability of Pinyin.

X. Misreading and Correction of Pinyin

In the process of learning pinyin, misreading is a common problem. These misunderstandings may be due to the ignorance of pinyin rules or the influence of mother tongue pronunciation habits. Understanding common misreading types and their correction methods can help learners master pinyin more effectively. There are many types of misreading of pinyin, such as misreading of initials, misreading of finals, misreading of tones, etc. These misunderstandings may be due to the ignorance of pinyin rules or the influence of mother tongue pronunciation habits. For example, some learners may misread "zh" in pinyin as "z" because the initial "zh" does not exist in their mother tongue. Correcting the misreading of pinyin requires combining phonetics principles with actual pronunciation practice, and gradually mastering the correct pronunciation of pinyin through repeated practice and correction.

XI. Variations and Special Rules of Pinyin

Besides the basic pinyin rules, there are some variations and special rules in pinyin. These variations and rules reflect the complexity and diversity of Chinese pronunciation. Understanding these variations and rules can help learners master pinyin more comprehensively and use it flexibly in different language environments. The variations and special rules of Pinyin include light tone, consonant, linking and so on. These variations and rules reflect the complexity and diversity of Chinese pronunciation. For example, light tone is a special tone in Chinese. Its pronunciation is light and short, and it is usually used for some function words and suffixes. Erhua is a special pronunciation phenomenon in Chinese, which is expressed by adding "r" after the vowel, and is usually used in some nouns and adjectives. Linking is a special pronunciation phenomenon in Chinese, which is expressed by fast linking between two syllables and is usually used in some fixed phrases and idioms. Understanding these variations and rules can help learners master pinyin more comprehensively and use it flexibly in different language environments.

XII. The Future Development and Challenges of Pinyin

With the development of society and the change of language, Pinyin is also facing new development and challenges. For example, how to adapt to the emergence of new words, how to deal with the relationship between dialects and Putonghua, and how to better apply Pinyin in information technology. Exploring the future development of Pinyin will not only contribute to the further improvement of Pinyin, but also contribute to the continued prosperity of Chinese. The future development of Pinyin needs to combine many factors such as linguistics, information technology and social needs. For example, with the emergence of new words, pinyin needs to be constantly updated and improved to meet the pronunciation and writing needs of new words. With the increasingly complex relationship between dialects and Putonghua, Pinyin needs to be constantly adjusted and optimized to better reflect the diversity and unity of Chinese. With the rapid development of information technology, pinyin needs constant innovation and application to improve the efficiency and accuracy of Chinese character input. The future development of Pinyin is not only related to the inheritance and development of Chinese, but also related to the status and influence of Chinese in international communication.

Through the detailed elaboration of the above twelve aspects, we can have a deeper understanding of the writing skills of Pinyin and the linguistic principles behind it. Pinyin is not only a tool to learn Chinese, but also a window to understand Chinese culture. Mastering pinyin writing skills is of great significance for improving Chinese learning efficiency, enhancing language expression ability and promoting international communication.

On September 8th, 2022, the online celebrity medical mask Fuerjia, which rose in recent years, made its debut on the Growth Enterprise Market of Shenzhen Stock Exchange, and will soon become another medical beauty concept stock in A shares. However, the IPO of New Economy noticed that the medical masks vigorously promoted by Fuerjia in hospitals and medical institutions contained preservatives with cancer risk, and its whitening masks were falsely publicized in the name of National Medical Products Administration.

Medical facial mask contains high-risk preservatives.

A consumer told the IPO of New Economy that she was recommended to buy Furjia medical repair patch after surgery in a medical and beauty institution. Unexpectedly, after using it, her face became swollen, red pimples and her eyes ached. She suspected that there were allergic substances in the ingredients of the mask, so she looked up the ingredient list and found that there were only three chemical ingredients besides sodium hyaluronate and water:Sodium ethyl paraben, sodium propyl paraben, carbomer 940.

After looking it up, she found that,Sodium ethyl p-hydroxybenzoate and sodium propyl p-hydroxybenzoate are preservatives, while carbomer 940 is a thickener.She suspected that preservatives caused skin allergic reactions.

So, what preservatives did Fuerjia add to this medical mask under the banner of postoperative repair and skin allergy prevention?

National Medical Products Administration official website found that Fuerjia Medical Sodium Hyaluronate Repair Patch applied for registration as the second class medical device in April 2021. The registrant is Harbin Beixing Pharmaceutical Co., Ltd., and the approver is Heilongjiang Drug Administration. The main components of the product are sodium hyaluronate, water for injection, sodium ethyl p-hydroxybenzoate, sodium propyl p-hydroxybenzoate, carbomer 940 and nonwovens. Its application scope is "used for mild and moderate acne, promoting wound healing and skin repair; It has an auxiliary therapeutic effect on early pigmentation and scar formation after acne healing, skin allergy and laser photon treatment. "

Let’s take a look at its components one by one.

Needless to say, sodium hyaluronate is hyaluronic acid. There is nothing to say about water for injection and nonwovens, which are normal medical accessories. Carbomer 940 is a thickener, which is often used in cosmetics.

According to public information, ethyl p-hydroxybenzoate and propyl p-hydroxybenzoate are efficient preservatives, and the combination of them can improve the anticorrosion ability and solubility. In order to extend the shelf life of cosmetics, different doses of preservatives are added, which is a routine operation. For example, the shelf life of facial masks is generally 2-3 years, and it is impossible to keep them for such a long time without adding preservatives.

However, it is worth noting that,The two preservatives used in Fuerjia medical sodium hyaluronate repair patch belong to nipagin ester preservatives, including methyl paraben, ethyl paraben, propyl paraben, butyl paraben and so on..

In recent years, there is a great controversy around nipagin ester preservatives. Previous studies have said thatExcessive use of parabens in cosmetics can cause contact dermatitis.A study by British medical staff shows that,The accumulation of nipagin ester in human body will increase the risk of breast cancer and uterine cancer in women.

Although the scientific community is rightThe carcinogenicity of nipagin ester is controversial, but considering its potential toxicity, the EUIn 2014, the amount of propyl paraben and butyl paraben was restricted, from the previously allowed amount of 0.4% for single use and 0.8% for mixed use to 0.14% for single use or joint use. In addition, these two preservatives are prohibited from being added to the diaper area of children under 3 years old.

At present, the general consensus in the industry is that,Methyl hydroxybenzoate and ethyl hydroxybenzoate are relatively safe at the legally limited concentration, but propyl 4-hydroxybenzoate and butyl hydroxybenzoate should be treated with caution.

The Fuerjia medical sodium hyaluronate repair patch does not disclose the specific dosage of its nipagin ester in the ingredient list.However, compared with ethylparaben, propyl 4-hydroxybenzoate has a higher risk, so it seems inappropriate to use it after medical and aesthetic surgery.

As far as the specific risks are concerned, a third-party cosmetics evaluation website made a simple comparison. The risk level of sodium hyaluronate and water used in Fuerjia medical repair patch is 1, which means it is very safe; However, the risk in propyl 4-hydroxybenzoate is as high as 7, which means that the risk is high.

Therefore, in Tik Tok and Xiaohongshu, some merchants with goods advertised that the production standard of mechanical brand medical beauty mask was higher and less preservatives were added, which could not stand scrutiny. At the very least, this medical repair patch of Volga uses a high-risk preservative and does not choose a safer substitute.

This not only reminds people of the carcinogen incident of Haitian soy sauce additives, which involves the carcinogen sodium benzoate. Like propyl paraben, sodium benzoate is a preservative, and sodium benzoate can react with vitamin C to generate carcinogenic benzene. For this reason, Japan and other countries have stopped producing sodium benzoate and restricted its use.

Invisible preservative hiding behind the scenes

Compared with the above preservatives, there is also a kind of "invisible" preservatives in cosmetics. These preservatives are no longer on the public list of preservatives, but they can still play an antiseptic role. Furga’s cosmetic mask has a similar operation. For example, in the Volga Nicotinamide Whitening and Spotting Repair Mask, the new economic IPO found that,Volga used the classic combination of "p-hydroxyacetophenone" and "1,2 hexanediol".

According to public information,1,2- Hexanediol is a polyol.At present, it is not listed as a preservative, but defined as a humectant and a penetration aid. Usually, the addition of about 5% will have a clear antiseptic effect.

P-hydroxyacetophenone is a natural antioxidant component in plants, and it is a new preservative substitute product. It can be compounded with hexanediol and propylene glycol to replace traditional preservatives.

In the product formula submitted by Volga to the State Food and Drug Administration,P-hydroxyacetophenone and 1,2-hexanediol are widely used, and the purpose of use is marked as "moisturizing", "freckle" and "conditioner". But in fact, they have only one purpose: anti-corrosion.

Why can’t we just label it "preservative"?

This is because "p-hydroxyacetophenone" and "1,2 hexanediol" are on the list of 51 preservatives stipulated by the state. However, when declaring the purpose of use, these two materials can’t pass if they are preservatives, but they can be called moisturizers/skin conditioners.

The new economy IPO noticed that in addition to preservatives, there is another very interesting ingredient in the Vulgar whitening mask:Hydroxyethyl piperazine ethanesulfonic acid.

Hydroxyethyl piperazine ethanesulfonic acid is often used as a buffer in the laboratory. It has the effect of exfoliating keratin when used in cosmetics, which can help remove aged keratin on the skin surface and increase the absorption of active ingredients. However, it should be noted that,When using hydroxyethyl piperazine ethanesulfonic acid, it is necessary to avoid light, otherwise it will produce hydrogen peroxide (that is, hydrogen peroxide). Therefore, the mask added with this material is suitable for use at night.

Interestingly, Fuerjia Whitening Mask was actually played in the publicity copy of an e-commerce channel."Full scene whitening", "protection before sun exposure" and "repair after sun exposure"The words, this is to let female consumers produce toxins on their faces and destroy themselves?

Stealing the name of National Medical Products Administration for false propaganda.

In addition to his poor understanding of product safety and his mistakes in using scenes for publicity, Fuerjia was also suspected of embezzling National Medical Products Administration’s name for false publicity.

On the page of JD.COM Volga Nicotinamide Whitening and Spotting Repair Mask,Its products call themselves "whitening special certificate holder", and publicly declare that the products have "freckle whitening special certificate".The picture below shows the registration certificate of Volga Nicotinamide Whitening and Spotting Repair Mask, stamped by National Medical Products Administration.

This is equivalent to telling consumers that this whitening and freckle-removing mask holds the "freckle-removing and whitening certification certificate" issued by National Medical Products Administration. What is the truth? Will National Medical Products Administration really endorse the efficacy of a mask?

In National Medical Products Administration official website, Furjia Nicotinamide Whitening and Spotting Repair Mask was registered and approved as a domestic cosmetic in October 2020. However, in the remarks, National Medical Products Administration solemnly declared that,"National Medical Products Administration has not organized an audit of the alleged efficacy of this product, and this approval document is not regarded as an approval of the alleged efficacy of the product."

It can be seen that National Medical Products Administration only provides a product registration certificate, not a product certification certificate. Fuerjia used tiger skin as a banner, distorted the original intention of National Medical Products Administration’s registration certificate, and made false endorsements for its products.
