Perhaps you should try some spelling variations:
cohen wang » chen wang
sin dank » ein dank, mein dank, sein dann
wang lei » wang wei, wang fei, wang li
yang yue » wang yue, yang yun, yang jui
j cohen » m cohen, _ cohen, i cohen
yang yi » yang di, yang jui
yang xi » yang di, yang jui
dank j » dank 1, dank i, dank 2
dong » doing, long, done

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: dong sin dank j cohen wang lei ((((yang yue) OR (yang yi))) OR (((yang judy) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin dank j cohen wang lei ((((yang yue) or (yang yi))) or (((yang judy) or (yang xi)))) ;*.
