Perhaps you should try some spelling variations:
yan yang » yang yang, yao yang, dan yang
yang zhi » wang zhi, yan zhi, liang zhi
zhi best » i best, iii best
yang jin » yang jie, yang jun, ying jin
wong sau » wong sam, wong siu, wong shiu
yan jiu » yang jie, pang jiu
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan yang zhi best ((yan jiu) or (yang jin)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan yang zhi best ((yan jiu) OR (yang jin)) wong sau ;*.
