Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung thanh, trung tam, tran tuan
hoc chieu » hoc thieu, ho chieu, hoc hien
trung cua » truong cua, trung cap, dung cua
thanh ban » thanh san, thanh van, thanh bac
cong van » cong vang, cong san, song van
cong tac » cong ty

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: hoc chieu xanh - thanh ((trung cua) OR (trung tuan)) nhung ((cong van) OR (cong tac)) thanh ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - thanh ((trung cua) OR (trung tuan)) nhung ((cong van) or (cong tac)) thanh ban~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - thanh ((trung cua) OR (trung tuan)) nhung ((cong van) or (cong tac)) thanh ban*.
