Perhaps you should try some spelling variations:
thanh tung » thanh cong
tieu danh » dieu danh, tiep danh, thien danh
tung tran » trung tran, hung tran, huong tran
tran hung » tran hong, tran quang, tran hoang
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 danh - thanh tung tran hung cong tac ((than cap) OR (toan cau))~.
• Adding a wildcard symbol may retrieve word variants: theo tieu danh - thanh tung tran hung cong tac ((than cap) or (toan cau))*.
