Perhaps you should try some spelling variations:
yuan ming » yuan ting, kian ming, tuan minh
ming tang » ming hung, ming kong, ming qing
roa yuan » roa juan, from yuan
tang min » chang min, sang minh, yang mind
min cong » minh cong, min hong, min jeong
yang 47 » yang 4, yang 4.3
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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: ((yang 47) OR (((yang xi) OR (yang yi))))ng roa yuan ming tang min cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang 47) or (((yang xi) OR (yang yi))))ng roa yuan ming tang min cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang 47) or (((yang xi) OR (yang yi))))ng roa yuan ming tang min cong shu ;*.
