Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
hua gain » heat gain, run gain, hua ban
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai
man tan » man han, man tun, tan tan
man can » man han, woman can, man kann
yang yi » yang di, yang xi, yang jui

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: wan ((man tan) OR (man can)) hua gain ((yang liang) OR (((yang jin) OR (yang yi)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((man tan) OR (man can)) hua gain ((yang liang) or (((yang jin) or (yang yi)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((man tan) OR (man can)) hua gain ((yang liang) or (((yang jin) or (yang yi)))) hong hai ;*.
