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