Perhaps you should try some spelling variations:
hang weng » huang weng, hang seng
chih hang » chin chang, shih huang, chih yung
weng fang » jing fang, wen wang
dan yang » daun yang, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
wen chih » wen chin, chen chih, lin chih
fang shu » fang zhou, cong shu, tan shu

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 ((dan yang) OR (tan yang)) wen chih hang weng fang shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((dan yang) or (tan yang)) wen chih hang weng fang shu ;*.
