Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
huei ying » hui ying, hoi ying
tan chia » tuan china, than china, can china
pei yang » wei yang, hui yang, pei yun
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: ((yang yang) OR (yang guang)) tan chia ((pei yang) OR (huei ying)) 3.2 ((long do) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang guang)) tan chia ((pei yang) or (huei ying)) 3.2 ((long do) OR (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang guang)) tan chia ((pei yang) or (huei ying)) 3.2 ((long do) OR (long d)) ;*.
