Perhaps you should try some spelling variations:
trung thanh » truong thanh
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung tam, tran tuan, truong thanh
thong cong » trong cong, tong cong, thong thong
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh lap, thanh cac
phan cau » phan dau, phan cac, phan tu

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 xanh - thanh ((trung tuan) OR (trung thanh)) thong cong dan ((than cap) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - thanh ((trung tuan) OR (trung thanh)) thong cong dan ((than cap) or (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh ((trung tuan) OR (trung thanh)) thong cong dan ((than cap) or (phan cau))*.
