Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
chu xanh » chu manh, chua xang, chuc danh
cong tac » cong ty
tac phan » tac pham, tai phan, tac phat
phan lap » phan dau

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: theo ((chu xanh) OR (chieu xanh)) - thanh ((trung cua) OR (trung cap)) trong cong tac phan lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chieu xanh)) - thanh ((trung cua) or (trung cap)) trong cong tac phan lap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chieu xanh)) - thanh ((trung cua) or (trung cap)) trong cong tac phan lap*.
