Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, ho chieu, thi chieu
trung cap » truong cao, trung tam
hang cong » dang cong, hang nong, thanh cong
bang cong » dang cong, bang song, dung cong
theo chu » cho chu, chao chu, theo yeu
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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 chu) OR (theo chieu)) xanh - thanh trung cap ((hang cong) OR (bang cong)) dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (theo chieu)) xanh - thanh trung cap ((hang cong) or (bang cong)) dan than cap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (theo chieu)) xanh - thanh trung cap ((hang cong) or (bang cong)) dan than cap*.
