Perhaps you should try some spelling variations:
thanh trung » thanh tung
thong cong » trong cong, tong cong, thong thong
trung nam » trung tam, trong nam, trung cap
nam thong » nam trong, nam thang, nam phong
doan phan » doanh phan, toan phan, doanh nhan
doc hieu » toc thieu, hoc thieu
dan phan » dan chan, van phan, dam phan

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 hien) OR (doc hieu)) xanh - thanh trung nam thong cong ((dan phan) OR (doan phan)) cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hien) or (doc hieu)) xanh - thanh trung nam thong cong ((dan phan) OR (doan phan)) cac~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hien) or (doc hieu)) xanh - thanh trung nam thong cong ((dan phan) OR (doan phan)) cac*.
