Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trung » thanh trung, hanh trang, manh trung
trung kha » trung khoa, trung ha, truong khoa
nang cong » nang song, dang cong, bang cong
kha nang » phap nang, ky nang, ki nang
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban

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) OR (chieu tinh)) - hanh trung kha nang cong dan toan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - hanh trung kha nang cong dan toan ban*.
