Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
hui ying » huei ying, hoi ying, hui ping
wei yang » pei yang, wei wang, wei yang's
tan hua » tuan hua, wang hua, tan chia
long do » long du, longer do, long ago
long d » long du, long _, long 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: ((yan liang) OR (yang liang)) tan hua ((hui ying) OR (wei yang)) 3 ((long d) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang liang)) tan hua ((hui ying) or (wei yang)) 3 ((long d) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang liang)) tan hua ((hui ying) or (wei yang)) 3 ((long d) OR (long do)) ;*.
