Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
tuan hua » tuan vu, yuan hui
pei yang » wei yang, hui yang, pei yun
yang jui » yang judy, yang di, yang xi
tan hua » wang hua, tan chia, tan puay
long do » long d, long du, longer do

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (yang guang)) ((tan hua) OR (tuan hua)) pei yang jui ((long did) or (long do)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (yang guang)) ((tan hua) OR (tuan hua)) pei yang jui ((long did) OR (long do)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang guang)) ((tan hua) OR (tuan hua)) pei yang jui ((long did) or (long do)) ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang guang)) ((tan hua) OR (tuan hua)) pei yang jui ((long did) or (long do)) ;*.
