Perhaps you should try some spelling variations:
wang yuhan » wang luhang, wang yan, wang yidan
fang yuan » wang yan, meng yuan, tang yun
wong yue » wang yue, hong yu
dr rene » der rent
tian yi » qian yi, tian yu, tan yi
yi wong » yi rong, y wong, kie wong
erence » terence, terrence

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

• If you are trying to use Boolean operators, they must be ALL CAPS: yang ((fang yuan) OR (wang yuhan)) ((dr rene) OR (di erence)) tian yi wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((fang yuan) OR (wang yuhan)) ((dr rene) or (di erence)) tian yi wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((fang yuan) OR (wang yuhan)) ((dr rene) or (di erence)) tian yi wong yue ;*.
