Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung don
theo lieu » theo tieu, theo chieu, theo yeu
lieu tinh » trieu tinh, diep tinh, bien tinh
hanh dang » hanh dong, hanh dung, hanh mang
dung cong » dung trong
anh dang » anh dong, anh dung, anh bang
van tuan » van quan, van ban, anh tuan
tuan ban » tuan bang, toan ban, luan ban

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: theo lieu tinh - ((hanh dang) OR (anh dang)) cua ((nhung cong) OR (dung cong)) van tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo lieu tinh - ((hanh dang) or (anh dang)) cua ((nhung cong) OR (dung cong)) van tuan ban~".
• Adding a wildcard symbol may retrieve word variants: theo lieu tinh - ((hanh dang) or (anh dang)) cua ((nhung cong) OR (dung cong)) van tuan ban*.
