Perhaps you should try some spelling variations:
thanh trung » thanh tung
thong cong » trong cong, thong thong, phong chong
tieu xanh » tieu danh, chieu xanh, dieu hanh
dieu danh » dieu hanh, tieu danh, dia danh
tong cong » trong cong, cong cong, dung cong
trung ha » trung hoc, trung tam, trung cap
anh toan » manh toan, anh tuan, thanh 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 ((tieu xanh) OR (dieu danh)) - thanh trung ha ((thong cong) OR (tong cong)) anh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) or (dieu danh)) - thanh trung ha ((thong cong) OR (tong cong)) anh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) or (dieu danh)) - thanh trung ha ((thong cong) OR (tong cong)) anh toan cau*.
