Perhaps you should try some spelling variations:
wang liang » wang yang
zhang jian » zhang fan, shang jin
ping wang » ping pong, hong wang
liang zhi » liang zhu, wang zhi, liang li
zhang min » zhang ming, zhang xin, chang min
zhi sign » i sign, ni sign
wong siu » wong shiu, kong siu, wong sau

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: ping wang liang zhi sign ((zhang min) OR (zhang jian)) wong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ping wang liang zhi sign ((zhang min) or (zhang jian)) wong siu ;*.
