Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
doan tien » doan thien, doanh tien, toan tien
thi dung » thi huong, thi nhung, thi nang
thi cong » thien cong
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cau » toan cao, toan ban, toan tap

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 thinh - hanh trinh ((thi dung) OR (((thi cong) OR (tai cong)))) cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan tien thinh - hanh trinh ((thi dung) or (((thi cong) OR (tai cong)))) cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: doan tien thinh - hanh trinh ((thi dung) or (((thi cong) OR (tai cong)))) cong tan toan cau*.
