hua gain » heat gain, hua ban, via gain
run gain » run pain
yang jin » yang jie, yang jun, 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: ((yang yang) or (wang ryan)) tuan ((hua gain) OR (run gain)) yang jin dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (wang ryan)) tuan ((hua gain) OR (run gain)) yang jin dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (wang ryan)) tuan ((hua gain) OR (run gain)) yang jin dang hai ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (wang ryan)) tuan ((hua gain) OR (run gain)) yang jin dang hai ;*.
