Perhaps you should try some spelling variations:
cong doanh » cong danh, cong doan, rong doanh
dong doanh » dung doanh, trong doanh, doanh doanh
lieu tinh » trieu tinh, diep tinh, bien tinh
canh manh » lanh manh, canh tranh, cach mang
manh cua » doanh cua, ban cua
cua dung » cua dang, cua dong, qua dung
phan cac » nhan cach, phan dau, phan lap
ho lieu » so lieu, co lieu, ho kieu

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - canh manh cua dung ((cong doanh) OR (dong doanh)) phan cac~".
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - canh manh cua dung ((cong doanh) OR (dong doanh)) phan cac*.
