Perhaps you should try some spelling variations:
chon chinh » cho chinh, thon chinh, chinh chinh
trung tuan » trung thanh, trung tam, tran tuan
trung cua » truong cua, trung cap, dung cua
hang cong » hang nong, bang cong, thanh cong
dang cong » dung cong
dan than » dan chan, ban than, van than
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: chon chinh sach - thanh ((trung cua) OR (trung tuan)) ((hang cong) OR (dang cong)) dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chon chinh sach - thanh ((trung cua) OR (trung tuan)) ((hang cong) or (dang cong)) dan than cap~".
• Adding a wildcard symbol may retrieve word variants: chon chinh sach - thanh ((trung cua) OR (trung tuan)) ((hang cong) or (dang cong)) dan than cap*.
