衷心的问候
你好
You can use "Best regards," (followed by a comma) in the closing of a business or friendly letter. On the next line, you can write your signature. If you are typing the letter, leave a blank line between "Best regards," and your typed name. In the blank line, write your signature.

I think you mean how do you write in using Mandarin characters ? 住 在 zhu zai = to live (in )
Chinese mandarin is hao yun
Well, you use thank you either if it's a formal letter (and in any part of it) or not while you normally use best regards at the end of a formal letter

Seeing as we cannot print in Mandarin on this site, there is no way to answer that.
