Perhaps you should try some spelling variations:
wang liang » wang yang
yan liang » yang liang, you liang, yan wang
yan guan » gan guan, yan yuan, yang guang
hua gain » heat gain, hua ban, via gain
run gain » run pain
yang jin » yang jie, yang jun, ying jin
wai yan » wang yan, wei yang
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: wai yan guan ((hua gain) OR (run gain)) ((((yan liang) or (wang liang))) or (yang jin)) dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wai yan guan ((hua gain) OR (run gain)) ((((yan liang) OR (wang liang))) OR (yang jin)) dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan guan ((hua gain) OR (run gain)) ((((yan liang) or (wang liang))) or (yang jin)) dang hai ;".
• Adding a wildcard symbol may retrieve word variants: wai yan guan ((hua gain) OR (run gain)) ((((yan liang) or (wang liang))) or (yang jin)) dang hai ;*.
