Perhaps you should try some spelling variations:
kong hang » kong heng, kong hong, kong land
yan yang » yang yang, yao yang, tan yang
dan yang » daun yang, tan yang, wang yang
law hong » how hong, law ho, law how
law long » how long, law land, law loan
hang shu » zhang shuo, cong shu, chang su
wang » wing, wan

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 OR lang) ((yan yang) OR (dan yang)) li ((law hong) OR (law long)) kong hang shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((yan yang) or (dan yang)) li ((law hong) OR (law long)) kong hang shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((yan yang) or (dan yang)) li ((law hong) OR (law long)) kong hang shu ;*.
