Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
thien chi » trien chi, thien chien, thien chinh
tranh van » tran van, trinh van, thanh van
van thong » van thuong, van phong, va thong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan tap
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban
chi van » thi van, chu van

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: thien chi van - canh tranh van thong cong tan ((((toan cau) OR (toan tai))) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: thien chi van - canh tranh van thong cong tan ((((toan cau) or (toan tai))) or (toan ban))*.
