Perhaps you should try some spelling variations:
tong hang » kong hang, yong phang, long han
yan yang » yang yang, yao yang, dan yang
tan yang » dan yang, tan ying, tan yong
tan chor » san cho, tan chia, tan poor
hang shu » zhang shuo, cong shu, chang su
lan cho » san cho
wang » wing, wan, lang

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 ((yan yang) OR (tan yang)) li ((lan cho) OR (tan chor)) tong hang shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) or (tan yang)) li ((lan cho) OR (tan chor)) tong hang shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) or (tan yang)) li ((lan cho) OR (tan chor)) tong hang shu ;*.
