Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
theo dieu » theo tieu, theo chieu, thuoc dieu
dieu danh » dieu hanh, tieu danh, dia danh
thong cua » thong quan, thong tu
huong cua » dung cua
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van 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: theo dieu danh - hanh ((thong cua) OR (huong cua)) thong cong tan toan cao~.
• Adding a wildcard symbol may retrieve word variants: theo dieu danh - hanh ((thong cua) or (huong cua)) thong cong tan toan cao*.
