Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
trung quan » truong quan, trong quan, truong quang
trung tuan » trung thanh, trung tam, tran tuan
ho chieu » hoc thieu, doi chieu, mot chieu
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: ((ho chieu) OR (theo chieu)) xanh - thanh ((trung quan) OR (trung tuan)) trong cong tac toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - thanh ((trung quan) or (trung tuan)) trong cong tac toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - thanh ((trung quan) or (trung tuan)) trong cong tac toan tap*.
