Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu
doanh cua » doanh luan
tang cua » mang cua, hang cua, tang luan
cong ban » cong bang, cong san, cong tan
ban than » ban thanh, van thanh, ban hang
than cau » toan cau, phan cau, than cap

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: ((hoc thieu) OR (hoc hien)) khang - hanh ((doanh cua) OR (tang cua)) nhung cong ban than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) khang - hanh ((doanh cua) or (tang cua)) nhung cong ban than cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) khang - hanh ((doanh cua) or (tang cua)) nhung cong ban than cau*.
