Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trang tuan » tran tuan, trong tuan, tran xuan
trung tuan » trung thanh, trung tam, tran tuan
hoc chieu » hoc thieu, ho chieu, hoc hien
dung cong » dung trong
cong tac » cong ty
tac doan » tap doan, tan doan, thai doan
doan tap » toan tap, doan cap, doanh tai

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 - hanh ((trang tuan) OR (trung tuan)) dung cong tac doan tap~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh ((trang tuan) or (trung tuan)) dung cong tac doan tap*.
