Perhaps you should try some spelling variations:
yun gain » you gain, n gain, yun hin
run gain » run pain
yang gai » yang dali, yang di, yang jui
gai gang » ngai hang, ii gang, i gang
gang hai » dang hai, shang hai, eang hay
yan yan » yan yuan, nan yan, yang yang
wang » wing, wan, lang

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yan ((yun gain) OR (run gain)) yang gai gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yan ((yun gain) OR (run gain)) yang gai gang hai ;*.
