Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, yin yang
yang yue » yang yun, yang jui, yang yi
wang yue » wong yue, wang hua, wang he
tan yang » dan yang, tan ying, tao yang
tan yong » tan hong, tan kong, tan ying
zong hai » hong hai, dang hai, long han
yi zong » yi rong, lin zong

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan ((yang yue) or (wang yue)) ((gain yang) or (((tan yang) OR (tan yong)))) yi zong hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((yang yue) OR (wang yue)) ((gain yang) OR (((tan yang) OR (tan yong)))) yi zong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yang yue) or (wang yue)) ((gain yang) or (((tan yang) OR (tan yong)))) yi zong hai ;".
• Adding a wildcard symbol may retrieve word variants: wang yan ((yang yue) or (wang yue)) ((gain yang) or (((tan yang) OR (tan yong)))) yi zong hai ;*.
