Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu manh » hieu nganh, dieu hanh, hien hanh
trung cap » truong cao, trung tam
tong cong » cong cong, dung cong, dang cong
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, 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: ho ((hieu manh) OR (chieu xanh)) - thanh trung cap ((tong cong) OR (trong cong)) dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu xanh)) - thanh trung cap ((tong cong) OR (trong cong)) dan than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu xanh)) - thanh trung cap ((tong cong) OR (trong cong)) dan than cau*.
