Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
manh trung » manh tung, thanh trung, manh hung
nhung cong » dung cong, thong cong, hang cong
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
chan ban » can ban, chan nan, chan doan
chat ban » nhat ban, chat ran, cua 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)) - manh trung cua nhung cong dan ((chan ban) OR (chat ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu tinh)) - manh trung cua nhung cong dan ((chan ban) or (chat ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) OR (chieu tinh)) - manh trung cua nhung cong dan ((chan ban) or (chat ban))*.
