Perhaps you should try some spelling variations:
wang yang » wang yanling
yang john » young john, king john, yang jin
john wong » john song, john bonn
tuan hua » tan hua, yuan hui
dan yang » daun yang, tan yang, yang yang
wong siu » wong shiu, kong siu, wong sau
tuan vu » thanh vu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang yang) or (wang liang))) or (wang yan)) ((tuan hua) OR (tuan vu)) dan yang john wong siu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (wang liang))) OR (wang yan)) ((tuan hua) OR (tuan vu)) dan yang john wong siu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) or (wang liang))) or (wang yan)) ((tuan hua) OR (tuan vu)) dan yang john wong siu ;".
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (wang liang))) or (wang yan)) ((tuan hua) OR (tuan vu)) dan yang john wong siu ;*.
