Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
lanh hanh » lanh manh, lenh hanh, xanh hanh
nang cong » nang song, dang cong, bang cong
cong dan » cong san, cong tan, huong dan
toan cao » toan tap
toan ban » van ban
hanh va » hang va, hanh vi
va nang » van nang, da nang, cam nang

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: theo ((chieu xanh) OR (chieu tinh)) - lanh hanh va nang cong dan ((toan cao) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu tinh)) - lanh hanh va nang cong dan ((toan cao) or (toan ban))*.
