Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, ho chieu, theo chu
trung tuan » trung thanh, trung tam, tran tuan
tuan thong » toan thong, tran thong, tuan phong
thong cong » trong cong, tong cong, thong thong
mot chieu » doi chieu, ho chieu
tan than » tan thanh, ban than, tam than

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: ((mot chieu) OR (theo chieu)) xanh - thanh trung tuan thong cong ((tan than) OR (tan tran)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (theo chieu)) xanh - thanh trung tuan thong cong ((tan than) OR (tan tran)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (theo chieu)) xanh - thanh trung tuan thong cong ((tan than) OR (tan tran)) cau*.
