Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tran » thanh trang, thanh toan, thanh tra
van chuong » van duong, van hung, van cong
thanh thao » thanh thanh, thanh thang, thanh pho
van phong » van dong, hai phong
thanh cao » thanh ca, thanh cac, thanh cham
ho chieu » theo chieu, hoc thieu, doi chieu

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 chieu xanh - thanh tran ((van chuong) OR (van phong)) dung tai ((thanh cao) OR (thanh thao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh tran ((van chuong) or (van phong)) dung tai ((thanh cao) OR (thanh thao))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh tran ((van chuong) or (van phong)) dung tai ((thanh cao) OR (thanh thao))*.
