大家好，很高兴在这里加入

I have registered on this site for a long time, but forgot my username and password, and after trying for a long time, it finally works. I also have a question, here is whether I can comment in English. I entered this content using a language translation application. thank you.

尽量使用中文，英文也不是不行，大部分人应该还是可以看明白的
