Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
zhong zhi » zhang zhi, zhong tai
yang yao » yang yang, wang yan, yang yi
hua gain » heat gain, run gain, hua ban
yang jin » yang jie, yang jun, ying jin
hong ghi » hong g, hong hai
yang ya » yang yi, yang ka, yang y

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang ya) or (yang yao))ng ya hua gain yang jin ((zhong zhi) OR (hong ghi)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang ya) OR (yang yao))ng ya hua gain yang jin ((zhong zhi) OR (hong ghi)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang ya) or (yang yao))ng ya hua gain yang jin ((zhong zhi) OR (hong ghi)) ;".
• Adding a wildcard symbol may retrieve word variants: ((yang ya) or (yang yao))ng ya hua gain yang jin ((zhong zhi) OR (hong ghi)) ;*.
