I can see people of different countries on this software. I feel very happy. I am a Chinese. I am a junior high school student in China.If you are willing to learn Chinese, you can ask me if you can't.In the language examination of the Chinese Opera and Dance Art Association, I have been tested from the first level to the 11th level, with a professional level of points that can be recognized.And as for why I use English, because English is generally familiar to everyone.As I said before, my English is not good, so why do I use English to post this post?It's very simple. I use English translation software. Finally, I really hope someone can teach me. Thanks!
