Shaanxi Normal University and teachers and students from Dongxiang County, Gansu Province jointly held a joint exhibition of calligraphy works and the promotion of the national standard language. Popularizing the standard spoken and written Chinese language is the responsibility stipulated in China's Constitution.
China has a vast territory and a large population, with multiple nationalities, languages, dialects and languages, and "books with the same language and same language" has been a dream that the Chinese nation has never stopped pursuing for thousands of years.
