Perhaps you should try some spelling variations:
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
doanh phan » doanh nhan, doan phan, doanh thanh
lieu tinh » trieu tinh, diep tinh, bien tinh
canh ban » can ban, canh dan, canh van
phan lap » phan dau
co lieu » cot lieu, co hieu, so lieu
ban cua » ban quan

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: co lieu tinh - canh ban cua ((nhung cong) OR (thong cong)) doanh phan lap~.
• Adding a wildcard symbol may retrieve word variants: co lieu tinh - canh ban cua ((nhung cong) or (thong cong)) doanh phan lap*.
