Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
chua nang » chuc nang, chua xang, kha nang
hanh manh » hanh mang, lanh manh, hoang manh
cua nhung » va nhung
manh cua » doanh cua, ban cua
cong ban » cong bang, cong san, cong dan
cong tan » cong tac, cong san, cong thanh
hang cau » hang dau, hang ca, nhung cau

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 sang) OR (chua nang)) - hanh manh cua nhung ((cong ban) OR (cong tan)) hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (chua nang)) - hanh manh cua nhung ((cong ban) OR (cong tan)) hang cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chua nang)) - hanh manh cua nhung ((cong ban) OR (cong tan)) hang cau*.
