Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wang yang » wang yan, wang liang, wang yanling
dang hari » dang hai
hua gain » heat gain, run gain, hua ban
yan han » yan zhang, kang han, yan clan
man han » man hat, man can, man kann
jing ji » ying jin

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 yang))) or (jing ji)) dang hari ;~.
• 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 yang))) OR (jing ji)) dang hari ;.
• 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 yang))) or (jing ji)) dang hari ;".
• Adding a wildcard symbol may retrieve word variants: wan ((yan han) OR (man han)) hua gain ((((yang liang) or (wang yang))) or (jing ji)) dang hari ;*.
