Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
tuan hua » tan hua, tuan vu, yuan hui
pei yang » hui yang, pei yun, yi yang
wei yang » wei wang, wei yang's, wei shang
mei yung » pei yun
de long » le long, de longue
long do » long d, long du, longer do

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