Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
shang kai » shang hai
yan ying » fan ying, ran ying, tan ying
ying hua » ming hua, wang hua, ying zhu
hua gain » heat gain, run gain, hua ban
yang jin » yang jie, yang jun, ying jin
wang » wing, wan, lang
hong » long

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 ying hua gain yang jin ((shang kai) OR (hong w)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ying hua gain yang jin ((shang kai) or (hong w)) ;*.
