Perhaps you should try some spelling variations:
nhanh lang » nhanh quang, nhanh thang, nhan dang
theo chieu » ho chieu, theo chu, thi chieu
phung cong » nhung cong, phong cong, nhung chong
hanh mang » nhanh mang, hanh trang, thanh hang
cua phung » cua phuong, cua nhung, cua chung
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: ((theo chieu) OR (theo tieu)) tinh - ((hanh mang) OR (nhanh lang)) cua phung cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (theo tieu)) tinh - ((hanh mang) OR (nhanh lang)) cua phung cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo tieu)) tinh - ((hanh mang) OR (nhanh lang)) cua phung cong tan toan cau*.
