Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang, yan guan
than china » tuan china, han china, wuhan china
china pei » china peo, china pim, china pt
long 2 » long _, long a, long d
yun 2 » yun _, run 2, tun 2
gun 2 » gen 2, run 2, tun 2

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang liang) OR (yang guang)) than china pei ((yun 2) OR (gun 2)) ((long 2) OR (longa 2)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang guang)) than china pei ((yun 2) or (gun 2)) ((long 2) or (longa 2)) ;*.
