Perhaps you should try some spelling variations:
mot trieu » mot chieu, mot tri, mon triet
nang cong » nang song, bang cong, hang cong
dang cong » dung cong
ho trieu » 25 trieu, 30 trieu, ho chieu
tranh va » tranh van, trang va, trinh va
tac phan » tac pham, tai phan, tac phat
phan cau » phan dau, phan cac, phan tu

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: ((ho trieu) OR (mot trieu)) tinh - canh tranh va ((nang cong) OR (dang cong)) tac phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (mot trieu)) tinh - canh tranh va ((nang cong) or (dang cong)) tac phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (mot trieu)) tinh - canh tranh va ((nang cong) or (dang cong)) tac phan cau*.
