Perhaps you should try some spelling variations:
thanh trung » thanh tung
hoc thieu » toc thieu, hoc hien
hang cong » dang cong, bang cong, thanh cong
hang nong » thang long, han tong
van nhanh » van thanh, van hanh, van khanh
nhanh cau » nhanh cay, thanh chau, nhanh ha
trung ha » trung hoc, trung tam, trung cap
doi chi » doi khi

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: ((doi chi) OR (hoc thieu)) xanh - thanh trung ha ((hang cong) OR (hang nong)) van nhanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chi) or (hoc thieu)) xanh - thanh trung ha ((hang cong) OR (hang nong)) van nhanh cau~".
• Adding a wildcard symbol may retrieve word variants: ((doi chi) or (hoc thieu)) xanh - thanh trung ha ((hang cong) OR (hang nong)) van nhanh cau*.
