Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » thong cong, hang cong, nhung don
hoc thieu » toc thieu, hoc hien
doanh cua » doanh luan
dung cong » dung trong
tang cua » mang cua, hang cua, tang luan
tan than » tan thanh, tan tran, ban than
than cap » khan cap, thanh lap, thanh cac

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 xanh - hanh ((doanh cua) OR (tang cua)) ((nhung cong) OR (dung cong)) tan than cap~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((doanh cua) or (tang cua)) ((nhung cong) or (dung cong)) tan than cap*.
