Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang
can child » care child, can build, cbt child
yan guan » gan guan, yan yuan, yihan guan
wen fang » weng fang, wen wang, yin fang
long do » long d, long du, longer do
fang 3 » fang _, fang a, gang 3
3 long » a long, 2 long, 3.2 long

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: ((yang liang) OR (((yang guang) OR (yan guan)))) ((can child) OR (can china)) wen fang 3 long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (((yang guang) or (yan guan)))) ((can child) OR (can china)) wen fang 3 long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (((yang guang) or (yan guan)))) ((can child) OR (can china)) wen fang 3 long do ;*.
