"Speak Mandarin and write standard words" should be written by hand.

The school is the foundation and important position for popularizing Putonghua and promoting standardized Chinese characters. Teachers and students in colleges and universities are an important army to promote Putonghua and standardize Chinese characters. We should take the lead in creating a standardized campus language environment in schools.

To create a standardized campus language environment, we must first establish a sense of standardization, clearly understand the significance of popularizing Putonghua and promoting standardized Chinese characters. Language is the most important communication tool and an important carrier of spreading culture in human society, and writing is the symbol of recording language. China has a vast territory, many ethnic groups, and many and complicated dialects in Chinese, which bring some difficulties to the communication between people from different regions and ethnic groups. As the only language that can cross the barrier of Chinese dialects and communicate with other brothers and nationalities, Mandarin has become the same language of the Chinese nation. Standardizing Chinese characters is the best tool to record this homonym. The standardization of spoken and written languages is related to national unity, national unity, economic development and social progress, which is of great significance.

To create a standardized campus language environment, we should also make clear the standard of language specification and the requirements for us. Putonghua takes Beijing pronunciation as the standard pronunciation, northern dialect as the basic dialect, and typical modern vernacular writings as the grammatical norm. The level standard of Putonghua proficiency test issued by the Ministry divides the level of speaking Putonghua into three levels, and each level is divided into two levels: A and B. Among them, the first level is standard Mandarin, the second level is relatively standard Mandarin, and the third level is ordinary Mandarin. The state has put forward different requirements for all kinds of employees who use Putonghua as their working language. At school, teachers are required to speak Mandarin in class, and teachers born after January 1, 1954 are also required to take the Putonghua proficiency test, and they must reach the second-class B level or above and hold relevant certificates. Students' Putonghua level is encouraged to be as high as possible, and students majoring in normal education must reach Grade II or above, otherwise they cannot graduate. Administrative cadres, on the other hand, reach the corresponding level according to the requirements of different age groups, among which young comrades require to reach the second-class B or above.

The state also requires schools to use Putonghua as the campus language, that is, teachers and students are required to speak Putonghua in formal occasions such as education, teaching, meetings, publicity and group activities, and everyone is encouraged to speak Putonghua in informal occasions on campus.

Standardized Chinese characters include simplified characters and other characters that need not be simplified. Promoting and using standardized Chinese characters means that we should not write typos, use nonstandard simplified characters, self-made characters and obsolete variant characters, and abuse traditional Chinese characters in written expressions for the public. In schools, standardized Chinese characters should be used for teaching, followed by standardized Chinese characters for public facilities (signboards, signs, etc.), official documents (official documents, seals, etc.), printed materials, and posting (notices, notices, posters, slogans and other promotional materials).

creating a standardized campus language environment is also an important aspect of promoting quality education and creating a civilized, elegant and positive campus cultural environment, and an important part of the school's spiritual civilization construction. Speaking Mandarin and writing standard characters is not only a matter of speaking and writing, it represents a person's language quality, and then it is related to a person's comprehensive quality and civilization. Language and writing are the carriers of knowledge and culture. The improvement of Chinese quality is the basis for us to improve our ability to collect and process information, acquire new knowledge, analyze and solve problems, and it also has an inherent role in promoting the formation, development and play of our overall quality. The improvement of everyone's overall quality will have a good aggregation effect on the campus cultural environment. The standardized campus language environment is an organic part of the tangible campus cultural environment.

Let's work together, everyone speaks Mandarin and writes standardized words, and do our best to create a standardized campus language and writing environment, so that the standardization of language and writing in our school can reach a new level under the current excellent situation.
