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
lanh manh » lanh tranh, lan anh, anh anh
van manh » van minh, van anh, van hanh
phan lap » phan dau
co lieu » cot lieu, co hieu, so lieu

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 - ((lanh manh) OR (van manh)) cua ((nhung cong) OR (thong cong)) doanh phan lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "co lieu tinh - ((lanh manh) OR (van manh)) cua ((nhung cong) or (thong cong)) doanh phan lap~".
• Adding a wildcard symbol may retrieve word variants: co lieu tinh - ((lanh manh) OR (van manh)) cua ((nhung cong) or (thong cong)) doanh phan lap*.
