Perhaps you should try some spelling variations:
wang yuhan » wang luhang, wang yan, wang yidan
yuhan fei » yuan fei, han fei, yan fei
liang wei » xiang wei, zhang wei, wang wei
hong than » hong tan, long thanh, hong hai
liang li » ling li, qiang li, liang zhi
yang lin » yang jin, wang lin, yang li
yu chen » yu cheng, yi chen, yulu chen

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: wang yuhan fei yu chen ((((liang li) OR (liang wei))) OR (yang lin)) hong than ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yuhan fei yu chen ((((liang li) OR (liang wei))) or (yang lin)) hong than ;~".
• Adding a wildcard symbol may retrieve word variants: wang yuhan fei yu chen ((((liang li) OR (liang wei))) or (yang lin)) hong than ;*.
