Perhaps you should try some spelling variations:
tien thanh » tien thinh, tran thanh, den thanh
nhung cong » dung cong, thong cong, hang cong
doan tien » doan thien, doanh tien, toan tien
canh tinh » manh tinh, canh tranh, nhanh tinh
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
manh toan » thanh toan, anh tuan, tinh toan
he nhung » hee nhung, ve nhung, me nhung
san toan » van toan, dan toan, xuan toan

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: doan tien thanh - ((canh tinh) OR (hanh tinh)) he nhung cong ((san toan) OR (manh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan tien thanh - ((canh tinh) OR (hanh tinh)) he nhung cong ((san toan) or (manh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: doan tien thanh - ((canh tinh) OR (hanh tinh)) he nhung cong ((san toan) or (manh toan)) cao*.
