Perhaps you should try some spelling variations:
wang kang » wang yang, wang liang, wang yan
yang yang » wang yang, wang yan
tan ying » fan ying, ran ying, tan yang
ying hai » ying hooi, dang hai, hong hai
han hua » wang hua, tuan hua
tan hua » tuan hua, wang hua, tan chia
tuan vu » thanh vu, tuan hua

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang kang ((((han hua) OR (tan hua))) or (tuan vu)) ((yang yang) or (tan ying)) li ying hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang kang ((((han hua) OR (tan hua))) OR (tuan vu)) ((yang yang) OR (tan ying)) li ying hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang kang ((((han hua) OR (tan hua))) or (tuan vu)) ((yang yang) or (tan ying)) li ying hai ;*".
