Perhaps you should try some spelling variations:
mot trieu » mot tri, mon triet, mot chieu
hanh mang » nhanh mang, hanh trang, nhanh lang
mang chua » mang cua, cong chua, cung chua
chua bang » chu bang, chua nang, chua xang
bang hang » ban hang, hang hang, nang hang
30 trieu » 25 trieu
va tuan » van tuan, va toan, a tuan
va quan » van quan, tac quan, hai quan

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((30 trieu) OR (mot trieu)) tinh - hanh mang chua bang hang ((va tuan) OR (va quan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((30 trieu) OR (mot trieu)) tinh - hanh mang chua bang hang ((va tuan) OR (va quan)) cau*.
