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
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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 - manh ((trung cua) OR (trung tuan)) dung cong dan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - manh ((trung cua) or (trung tuan)) dung cong dan ((toan cau) or (toan ban))*.
