Perhaps you should try some spelling variations:
chieu xanh » chieu tinh, hieu manh
chieu sang » hieu lang, nhieu tang
chieu sach » chinh sach, chiet tach, hieu cach
hanh trung » thanh trung, hanh trang, manh trung
nang cong » nang song, dang cong, bang cong
trung va » truong va, trang va, trung ha
cong ban » cong bang, cong san, cong tan
ban than » ban thanh, van thanh, ban hang
than cap » khan cap, thanh lap, thanh cac
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: hoc ((((chieu xanh) OR (chieu sang))) OR (chieu sach)) - hanh trung va nang cong ban than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((chieu xanh) OR (chieu sang))) or (chieu sach)) - hanh trung va nang cong ban than cap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((chieu xanh) OR (chieu sang))) or (chieu sach)) - hanh trung va nang cong ban than cap*.
