Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
wang yang » wang liang, wang yanling
yang yue » yang yun, yang jui, wong yue
wang yue » wong yue, wang hua, wang he
zong hai » hong hai, dang hai, long han
yang yi » yang di, yang xi, yang jui
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 yang) OR (wang yan)) ((yang yue) or (wang yue)) gain yang yi zong hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) ((yang yue) OR (wang yue)) gain yang yi zong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) OR (wang yan)) ((yang yue) or (wang yue)) gain yang yi zong hai ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) OR (wang yan)) ((yang yue) or (wang yue)) gain yang yi zong hai ;*.
