Perhaps you should try some spelling variations:
wang liang » wang yang
wang kang » wang yang, wang yan, wang yong
yang yang » wang yang, wang yan
tuan hua » tan hua, tuan vu, yuan hui
tan yang » dan yang, tan ying, tan yong
han hua » tan hua, wang hua
li dang » le dang, li gang, li wang
hai » hadi, haji, hari

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) OR (wang liang)) ((han hua) or (tuan hua)) ((yang yang) or (tan yang)) li dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang kang) OR (wang liang)) ((han hua) OR (tuan hua)) ((yang yang) OR (tan yang)) li dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang kang) OR (wang liang)) ((han hua) or (tuan hua)) ((yang yang) or (tan yang)) li dang hai ;".
• Adding a wildcard symbol may retrieve word variants: ((wang kang) OR (wang liang)) ((han hua) or (tuan hua)) ((yang yang) or (tan yang)) li dang hai ;*.
