Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yang minh » yang mind, anh minh, yang jin
sang minh » anh minh, song min, song ming
hua rene » hua ren, juan rene
yang yi » yang di, yang xi, yang jui
yi hua » li hua, ya hua, yi hui
cong » congo, long, hong

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 yang yi hua rene ((yang minh) OR (((kang minah) OR (sang minh)))) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang yi hua rene ((yang minh) or (((kang minah) OR (sang minh)))) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: yang yang yi hua rene ((yang minh) or (((kang minah) OR (sang minh)))) cong shu ;*.
