To learn Mandarin well, I think there are several essentials: First, learn pinyin letters well, master pronunciation parts, and practice some local dialects repeatedly until they are fully in place. Second, read more articles in Pinyin newspaper to exercise the feeling of speaking Mandarin, or after seeing a word, you will secretly recite its standard pronunciation, pay attention to the corresponding relationship with dialect pronunciation, so as to draw inferences and avoid analogy. Third, check if you don't understand. The dictionary is our good teacher. If you don't understand them, you should ask them modestly until they are completely correct. Pay special attention to the disyllabic and polysemy of some words. Fourth, read the dictionary and open the Modern Chinese Dictionary, word by word, word by word, sentence by sentence, page by page, with excellent results.
In addition, insist on daily conversation in Mandarin. Some people say that language depends on the environment. In an environment where everyone speaks Mandarin, I am very close to Zhu Bichi. Even if you have a strong accent, you will gradually get infected. In short, as long as you work hard, you can speak Mandarin well.
Through the study of Mandarin, I benefited a lot. I use Mandarin in class and try to communicate with my classmates after class. I feel that my standard of Putonghua is constantly improving. I believe that as long as my classmates speak Mandarin as often as I do, your Mandarin will definitely be better than mine!
