Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
cang thang » cong thanh, dang thanh
hoc thieu » toc thieu, hoc hien
cuong tap » luong tap, cong tac, luong tai
vat dung » van dung, viet dung, mat duong
tap doan » tap quan
doan ban » doanh ban, toan ban, doan van
va dung » van dung, va duong, va ung

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 - cang thang ((va dung) OR (vat dung)) cuong tap doan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - cang thang ((va dung) or (vat dung)) cuong tap doan ban*.
