Hello Meng Hua, and thanks for your interest in Wine! All Wine GSoC applicants must submit a patch to wine-devel (and presumably, have it accepted) before beginning GSoC. Find some small bug in Wine or something to improve and send a patch to show your skills. You'll want to read through the following pages:
https://wiki.winehq.org/Developer_FAQ
https://wiki.winehq.org/Submitting_Patches
https://wiki.winehq.org/Summer_Of_Code#Wine_and_the_Google_Summer_of_Code
If you have an idea for a patch but get stuck trying to make it work, you can always ask for help on this mailing list.
