Perhaps you should try some spelling variations:
yang cindy » yang mind
juan rene » juan meng, juan rana
hua chen » jui chen, yu chen, a chen
jong min » gong min, song min, song ming
yang jie » yang jin, yang di, yang jui
tong hui » wang hui
sin n » sin _
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 n ((juan rene) OR (hua chen)) ((((jong min) OR (yang cindy))) OR (yang jie)) tong hui ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin n ((juan rene) or (hua chen)) ((((jong min) or (yang cindy))) or (yang jie)) tong hui ;*.
