Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
zhong tai » hong tan, zhong zhi
hua gain » heat gain, run gain, hua ban
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, dang hai, hong tan
man han » man can, man kann, man what
hat » what, heat

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