Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu manh » hieu nganh, dieu hanh, hien hanh
hang hang » nang hang, cang thang, hung thang
cong vang » cong lang, cong quang, cong ngang
thanh cau » thanh chau, thanh mau, nhanh cau
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 ((hieu manh) OR (chieu xanh)) - hang hang va dung ((cong vang) OR (song van)) thanh cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (chieu xanh)) - hang hang va dung ((cong vang) or (song van)) thanh cau*.
