TOMHTML: A Proxy in China solved the problem.
By the way, it not only allows you to find musics but also let you listen & download it for free. I have some screenshots:
Google Music Home
The search engine of Google Music
After accepting their TOS, you can listen to the music you want without limitation. Also subtitle will be shown on the right sidebar while the singer is singing
You can download the music you want directly (no fees, no additional software required... ...)
