Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
cang thang » cong thanh, dang thanh
hoc chieu » hoc thieu, ho chieu, hoc hien
thanh mau » hanh mau, thanh san, thanh hai
thang va » hang va, trang va, thong va
cong tan » cong tac, cong san, cong thanh
song van » hoang van, trong van, duong van
va dung » van dung, va duong, vat dung

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 chieu xanh - cang thang va dung ((cong tan) OR (song van)) thanh mau~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - cang thang va dung ((cong tan) or (song van)) thanh mau*.
