Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
hanh doanh » hang doanh, chinh doanh, doanh doanh
hien quan » thien quan, lien quan, vien quan
hanh doan » thanh toan, thinh doan, nhanh hoan
va thong » va thuong, va phuong, he thong
cong van » cong vang, cong san, song van
toan ban » van ban
toan cao » 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: hoc hien quan - ((hanh doan) OR (hanh doanh)) va thong cong van ((toan ban) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: hoc hien quan - ((hanh doan) or (hanh doanh)) va thong cong van ((toan ban) or (toan cao))*.
