2. change
1. what to change
at the beginning, I suggest you do not modify it in disorder;

System \ etc, we recommend that you replace the two files, one is the hosts file and the other is apns-Conf, which is the APN access point. You can change the two files in notepad and save them directly, be sure not to "save "!
do not delete anything under System \ Lib. We recommend that you replace libicudata. so and other files (this is the sorting of contacts).

Ro. product. locale. you can change region = cn

Save the file after modification. Note that it is best to open the file in notepad and save it directly.
