Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
hanh doanh » hang doanh, doanh doanh, kinh doanh
luan dang » luan nang, luan danh, luan dong
cong tac » cong ty
pham cac » phan cac, pham ca, pham can
doi chi » doi khi
chi anh » chi danh, chi hanh, thi anh

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: doi chi anh - ((hanh doanh) or (chinh doanh)) luan dang ((cong san) OR (cong tac)) pham cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi anh - ((hanh doanh) OR (chinh doanh)) luan dang ((cong san) OR (cong tac)) pham cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi anh - ((hanh doanh) or (chinh doanh)) luan dang ((cong san) OR (cong tac)) pham cac*".
