Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hua gain » heat gain, run gain, hua ban
pang jun » yang jui
hong hai » shang hai, zhong tai, dang hai
man tan » man can, man han, tan tan
man tun » man tend, omar tun
yang xi » yang di, yang yi, yang jui

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 tan) OR (man tun)) hua gain ((yang yang) or (((pang jun) or (yang xi)))) hong hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((man tan) OR (man tun)) hua gain ((yang yang) OR (((pang jun) OR (yang xi)))) hong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((man tan) OR (man tun)) hua gain ((yang yang) or (((pang jun) or (yang xi)))) hong hai ;".
• Adding a wildcard symbol may retrieve word variants: wan ((man tan) OR (man tun)) hua gain ((yang yang) or (((pang jun) or (yang xi)))) hong hai ;*.
