Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
hua gain » heat gain, run gain, hua ban
kang han » kang chen, kong hang, zhang han
yang jin » yang jie, yang jun, ying jin
yan han » yan zhang, yan clan, yan guan
man han » man hat, man can, man kann
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 ((((yan han) OR (kang han))) or (man han)) hua gain ((yang liang) or (yang jin)) dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((((yan han) OR (kang han))) OR (man han)) hua gain ((yang liang) OR (yang jin)) dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((((yan han) OR (kang han))) or (man han)) hua gain ((yang liang) or (yang jin)) dang hai ;".
• Adding a wildcard symbol may retrieve word variants: wan ((((yan han) OR (kang han))) or (man han)) hua gain ((yang liang) or (yang jin)) dang hai ;*.
