hua gain » heat gain, run gain, hua ban
wang lin » wang li, wang qin, yang lin
pang jun » yang jui

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yan) OR (wang yang)) han hua gain ((wang lin) OR (pang jun)) dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((lang yan) or (wang yang)) han hua gain ((wang lin) or (pang jun)) dang hai ;*.
