Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
phan cong » thanh cong
chu xanh » chu manh, chua xang, chuc danh
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan tap » toan 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: theo ((chu xanh) OR (chieu xanh)) - hanh ((trang cua) OR (trung cua)) phan cong tac toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chieu xanh)) - hanh ((trang cua) OR (trung cua)) phan cong tac toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chieu xanh)) - hanh ((trang cua) OR (trung cua)) phan cong tac toan tap*.
