Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung don
theo tiem » theo tieu, them niem, thep tieu
tiem nang » tin nang, tich nang
hanh dung » thanh dung, anh dung, hanh dong
dung cong » dung trong
hang nong » thang long, han tong
dung cua » dung luan, dung cho
tan van » tran van, tang van, luan van

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: "theo tiem nang - hanh dung cua ((((nhung cong) OR (dung cong))) OR (hang nong)) tan van ban~".
• Adding a wildcard symbol may retrieve word variants: theo tiem nang - hanh dung cua ((((nhung cong) OR (dung cong))) OR (hang nong)) tan van ban*.
