Perhaps you should try some spelling variations:
yang liang » wang liang, peng liang, yang guang
yan liang » wang liang, you liang, yan wang
yang yang » wang yang, wang yan
tuan hua » tan hua, tuan vu, yuan hui
wei wang » wei yang, wen wang, wei shang
pei yun » lei kyun, mei yung, pei yang
de long » le long, de longue
long du » long d, long do, long run

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))) OR (yang yang)) tuan hua ((pei yun) OR (wei wang)) de long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan liang) OR (yang liang))) or (yang yang)) tuan hua ((pei yun) or (wei wang)) de long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yan liang) OR (yang liang))) or (yang yang)) tuan hua ((pei yun) or (wei wang)) de long du ;*.
