Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
quat trong » quan trong, luat trong, qua trong
doi chieu » doc hieu, doi chi, mot chieu
hanh dung » thanh dung, anh dung, hanh dong
dung quat » dung quan, dung qua, dung luat
ho chieu » hoc thieu, mot chieu, thi chieu
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cao » toan ban, toan tap

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 (doi chieu))) OR (theo chieu)) xanh - hanh dung quat trong cong tac toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ho chieu) OR (doi chieu))) or (theo chieu)) xanh - hanh dung quat trong cong tac toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((((ho chieu) OR (doi chieu))) or (theo chieu)) xanh - hanh dung quat trong cong tac toan cao*.
