Perhaps you should try some spelling variations:
hua gain » heat gain, run gain, hua ban
wenn man » kann man, wenn das
yang jie » yang jin, yang di, yang jui
wan man » woran man, kann man, wan ming
can hua » can hta, tan hua, can hurt
yang yi » yang di, yang jui
yang xi » yang di, yang jui
hai » hadi, haji, hari

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wan man) OR (wenn man)) can hua gain ((yang yi) or (((yang jie) or (yang xi)))) dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan man) OR (wenn man)) can hua gain ((yang yi) OR (((yang jie) OR (yang xi)))) dang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan man) OR (wenn man)) can hua gain ((yang yi) or (((yang jie) or (yang xi)))) dang hai ;*".
