Perhaps you should try some spelling variations:
nhanh tich » thanh tich, phan tich, thanh tinh
nhanh tinh » nhanh thanh, hanh trinh, nhan sinh
theo dieu » theo tieu, theo chieu, thuoc dieu
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
toan cao » toan ban, toan tap
va lang » va nang, hoa lang

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 dieu hanh - ((nhanh tich) OR (nhanh tinh)) va lang ((cong tan) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo dieu hanh - ((nhanh tich) OR (nhanh tinh)) va lang ((cong tan) or (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo dieu hanh - ((nhanh tich) OR (nhanh tinh)) va lang ((cong tan) or (cong san)) toan cao*.
