Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
hoang manh » hoang minh, hoang anh, hoang xanh
nhung cong » dung cong, thong cong, hang cong
hanh manh » hanh mang, lanh manh, thanh minh
cua nhung » va nhung
cong ban » cong bang, cong san, cong tan
ban than » ban thanh, van thanh, ban hang
than cau » toan cau, phan cau, than cap
chuc » thuc, chu, chua

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