Perhaps you should try some spelling variations:
gang minh » sang minh, kang minah, anh minh
yan yang » yang yang, yao yang, dan yang
long shu » cong shu, tong shui, long du
gong hui » tong hui, tong shui, wang hui
wai yan » wang yan, wei yang
dm vii » dm vi
di ii » dm ii
d ii » bd ii, d iii, i ii

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: wai yan yang ((di ii) OR (((dm vii) OR (d ii)))) gang minh ((long shu) OR (gong hui)) ;~.
• Adding a wildcard symbol may retrieve word variants: wai yan yang ((di ii) or (((dm vii) or (d ii)))) gang minh ((long shu) or (gong hui)) ;*.
