Perhaps you should try some spelling variations:
can child » care child, can build, can china
chen ping » chen rong, chen yang, chen wang
long tin » long tip, long trinh, long time
can chia » can china, tan chia, can asia
ping jia » jing jia, jing ji, ying jin
tong hui » wang hui
gong si » dong sin

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: long tin ((can chia) OR (can child)) chen ping jia ((tong hui) OR (gong si)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long tin ((can chia) OR (can child)) chen ping jia ((tong hui) or (gong si)) ;~".
• Adding a wildcard symbol may retrieve word variants: long tin ((can chia) OR (can child)) chen ping jia ((tong hui) or (gong si)) ;*.
