Perhaps you should try some spelling variations:
trong sinh » trong kinh, trong san
duong minh » duong manh, truong minh, thong minh
hieu lang » chieu sang, hieu quang, nhieu tang
nho hieu » nha hieu, nho sieu, nhu hieu
mang cua » manh cua, dung cua, cong cua
toan cau » toan cao, toan ban, toan tap
ban cua » ban quan

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: nho hieu lang - hanh ((mang cua) OR (ban cua)) dang ((trong sinh) OR (duong minh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nho hieu lang - hanh ((mang cua) OR (ban cua)) dang ((trong sinh) or (duong minh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: nho hieu lang - hanh ((mang cua) OR (ban cua)) dang ((trong sinh) or (duong minh)) toan cau*.
