Perhaps you should try some spelling variations:
huong tran » huong dan, quang tran, chuong trinh
tieu xanh » tieu danh, chieu xanh, dieu hanh
tung tran » trung tran, hung tran, quang tran
hung cong » nhung cong, hung cuong, phung cong
cong tac » cong ty
than cap » khan cap, thanh lap, thanh cac
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 tieu xanh - thanh ((tung tran) OR (huong tran)) hung cong tac ((than cap) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - thanh ((tung tran) OR (huong tran)) hung cong tac ((than cap) or (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - thanh ((tung tran) OR (huong tran)) hung cong tac ((than cap) or (toan cau))*.
