Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
hua gain » heat gain, run gain, hua ban
hong ghi » zhong zhi, hong g, hong hai
yan tan » tan tan, yan clan, yan guan
tan hua » tuan hua, wang hua, tan chia
yang li » yang lin, yang di, yang xi
wang » wing, wan, lang

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: wang yan tan hua gain yang li ((hong ghi) OR (hong w)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan tan hua gain yang li ((hong ghi) or (hong w)) ;*.
