Perhaps you should try some spelling variations:
thanh trung » thanh tung
khong cong » thong cong, khong cang, chong cong
chau tinh » cuu tinh, ha tinh, cac tinh
trung cua » truong cua, trung tuan, trung cap
cua khong » hua khong, cua phuong, cua thuong
cua tinh » cua sinh, va tinh, ha tinh
cong dan » cong san, cong tan, huong dan
toan ban » van ban
than cap » khan cap, thanh lap, thanh cac

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: ho ((chau tinh) OR (cua tinh)) - thanh trung cua khong cong dan ((toan ban) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) OR (cua tinh)) - thanh trung cua khong cong dan ((toan ban) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chau tinh) OR (cua tinh)) - thanh trung cua khong cong dan ((toan ban) or (than cap))*.
