Perhaps you should try some spelling variations:
yang guang » yang liang
yang yang » wang yang, wang yan
chia weng » chia wen, china wang
weng fang » jing fang, wen wang
yan guan » gan guan, yan yuan, yihan guan
tan chia » tuan china, than china, can china
long do » long du, longer do, long ago
fang 2 » fang _, fang a
long d » long du, long _, long 2

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 yang) OR (((yang guang) OR (yan guan)))) tan chia weng fang 2 ((long do) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (((yang guang) or (yan guan)))) tan chia weng fang 2 ((long do) OR (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (((yang guang) or (yan guan)))) tan chia weng fang 2 ((long do) OR (long d)) ;*.
