Perhaps you should try some spelling variations:
thanh trong » thanh trung, tranh trong, hanh trong
chieu xanh » chieu sach, chieu sang, chieu tinh
hien xanh » hien hanh, hien nhanh, hien khanh
trong cua » truong cua, thong cua, trong ca
dang cong » dung cong
cua dang » cua cong, cua ban
cong san » cong tac
than man » thanh san, tran manh, than phan
than ma » than va, khan ma, nhan ma

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 ((hien xanh) OR (chieu xanh)) - thanh trong cua dang cong san ((than man) OR (than ma))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (chieu xanh)) - thanh trong cua dang cong san ((than man) OR (than ma))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (chieu xanh)) - thanh trong cua dang cong san ((than man) OR (than ma))*.
