Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
tuan hua » tan hua, yuan hui
pei yang » wei yang, hui yang, pei yun
mei yung » pei yun, wei yang
tuan vu » thanh vu
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) OR (tuan vu)) ((pei 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) OR (tuan vu)) ((pei yang) or (mei yung)) de long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang guang)) ((tuan hua) OR (tuan vu)) ((pei yang) or (mei yung)) de long do ;*.
