Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
yan guan » gan guan, yan yuan, yang guang
wei wang » wei yang, wen wang, wei shang
tong hui » wang hui
tuan vu » thanh vu, tuan hua
wang li » wang lei, wang lin, tang li
li tong » li cong, li rong, li song

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 (yan liang))) OR (yan guan)) ((ya hua) OR (tuan vu)) wei wang li tong hui ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang liang) or (yan liang))) or (yan guan)) ((ya hua) or (tuan vu)) wei wang li tong hui ;*.
