Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
thong va » thong cua, truong va, thong qua
trang va » tran van
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cau » 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 tieu xanh - hanh ((((thong va) OR (hang va))) OR (trang va)) nhung cong tan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh ((((thong va) or (hang va))) or (trang va)) nhung cong tan toan cau*.
