Chinese Pinyin is a tool to assist Chinese pronunciation. Article 18 of the General Language and Characters Law of People's Republic of China (PRC) stipulates: "The Chinese Pinyin Scheme is a unified standard for spelling Roman letters in Chinese names, place names and Chinese documents, and it is used in areas where Chinese characters are inconvenient or unusable." The symbols written according to this set of norms are called Chinese Pinyin.

Chinese Pinyin is also an internationally recognized modern standard for Latin transliteration of Chinese. The international standard ISO 7098 (Chinese Roman alphabet spelling) writes: "The Chinese Pinyin Scheme officially adopted by the National People's Congress of the People's Republic of China (1958 February 1 1) is used for spelling Chinese. The scribe records the pronunciation of Chinese characters in Mandarin. "

Tone is an important part of Chinese syllables, which plays a unique role and is an indispensable element of syllables. Therefore, the Chinese Pinyin scheme specifically stipulates tone symbols. Tone symbol is the standard mode of inheriting phonetic symbols. These four key signature's intuitively show the rising and falling characteristics of the four tones in Putonghua, which has certain advantages. However, it is not convenient to return the pen when writing. Tone symbols are in the form of symbols, but the letters with symbols cannot be displayed and input correctly in the computer. This situation does not meet the current development requirements of informationization and digitalization. Because there is no corresponding code in the computer, these words can only be created by hand in published Chinese dictionaries and dictionaries. Many Chinese teachers in primary schools and universities are more worried about Chinese Pinyin. They simply can't produce electronic teaching materials of Chinese Pinyin that meet the requirements of the program, so they can only write by hand or make their own words, which brings great inconvenience to teaching. Flat tone, rising tone, rising tone and falling tone are traditional phonological terms, which are rarely used by non-professionals. The scheme should adopt the first, second, third and fourth tones commonly used by the public to name tone symbols. Tone symbols should be added after syllables, and the first sound, the second sound, the third sound and the fourth sound are recorded as -/v \ (all half-angle) respectively.
