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