Hi @Xinsheng1687, as others have mentioned, welcome to the forum! 
The forum has a “wishlist” category for community voting of features you would like to see added, changed or removed from MSFS. It is located here: #self-service:wishlist
Before posting, search to see if there’s an existing topic as we only want one topic per wished item. Creating a duplicate would split votes.
Officially, feedback and feature requests can be submitted to Zendesk.
There are 2 topics in the wishlist for adding of Chinese localization and World Update China, that you may wish to contribute to:
