Perhaps you should try some spelling variations:
wang luhang » wang liang, wang lihong, wang yuhan
wang zhang » wang zheng, zhang zhang, wang liang
chuan ping » chen ping, chuan bang
ying yang » yang yang, yin yang, ying chang
ping wang » ping pong, hong wang
ying han » ying chang, ying bank, ying jin

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 zhang) OR (wang luhang)) ((ying han) OR (ying yang)) chen chuan ping wang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang zhang) or (wang luhang)) ((ying han) OR (ying yang)) chen chuan ping wang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang zhang) or (wang luhang)) ((ying han) OR (ying yang)) chen chuan ping wang zhi ;*.
