2. Pinyin promotion:

Used to notate Chinese characters. Starting from the autumn of 1958, Chinese Pinyin was used to notate Chinese characters in primary school Chinese textbooks across the country, followed by middle school textbooks, dictionaries, and popular Chinese textbooks. Readers and literacy textbooks also use Chinese Pinyin notation. People's Daily and other newspapers use Chinese pinyin letters to notate difficult words.

In October 1958, the Central Administration for Industry and Commerce and the Chinese Character Reform Commission jointly issued a notice requiring the inclusion of Chinese pinyin letters on various trademark designs and product packaging. The names of postal and telecommunications offices, railway stations, weather stations, and city street names are also marked in Chinese pinyin.

On June 19, 1982, the National Bureau of Standards issued the national standard "Chinese Spelling of Titles of Chinese Books and Periodicals", which stipulates that Chinese books and periodicals published in China must be marked on the cover, front page, back cover, or copyright page. Book titles and journal titles in Chinese pinyin.

For teaching Mandarin, after the announcement of the "Chinese Pinyin Plan", Mandarin textbooks, reading materials, word lists, dictionaries, and dictionaries written using Chinese Pinyin were successively published, promoting the promotion and popularization of Mandarin. In teaching Chinese as a foreign language, the "Hanyu Pinyin Plan" has become an indispensable tool for foreigners to learn Chinese and conduct comprehensive training.
