Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
van nhuong » van chuong, van phuong, van huong
hoc thien » hoc thieu, hoc thiet, hoc tien
van nhung » va nhung, van hung, van phung
cong tac » cong ty
tac than » tac thanh, tam than, tac nhan
than cao » toan cao, thai cao, than cap

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: ((hoc thien) OR (hoc hien)) anh - thanh tran ((van nhung) OR (van nhuong)) cong tac than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) or (hoc hien)) anh - thanh tran ((van nhung) OR (van nhuong)) cong tac than cao~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) or (hoc hien)) anh - thanh tran ((van nhung) OR (van nhuong)) cong tac than cao*.
