China has a vast territory and many dialects. Because there are some obstacles in the communication between different dialects, which are not conducive to the economic and cultural exchanges between different places, the phenomenon of "regional cultural islands" has emerged. These "regional cultural islands" retain the essence of advanced culture and folk wisdom in different regions, but they cannot communicate and complement each other well because of language barriers. Therefore, a common language is needed to eliminate the "isolated island of regional culture" and bind all the wisdom in China's vast land. However, the promotion of a language is a long process, so don't rush it. It is necessary to handle the harmonious relationship between the development of local languages and the promotion of Putonghua. The goal of popularizing Putonghua is not to eliminate the local language, but to eliminate communication barriers. But the phenomenon of eliminating dialects (such as Nanning Pinghua and Vernacular) did appear in the promotion [1 1]? Therefore, when promoting, we should grasp the strength and understand the truth that too much is too late. Because the diversity of language has always been one of the precious cultural accumulations of Chinese civilization, just like the biodiversity in the biosphere, the world can be colorful because of diversity, and the biosphere can maintain balance to ensure the normal flow of materials and energy transfer. So is language. Because of the diversity of languages, it shows the inclusiveness and long-standing historical accumulation of Chinese culture. Because of diversity, all people will not look at and think in the same way.
There are some differences in pronunciation and vocabulary among Beijing dialect, mainland Mandarin, Taiwan Province Mandarin, Singaporean Mandarin and Malaysian Mandarin. It should be noted that Beijing dialect is not a standard language, because it is an unorganized and standardized Beijing urban dialect. The above standard languages are the products of standardization based on Beijing dialect.
