Perhaps you should try some spelling variations:
trung tuan » trung thanh, trung tam, tran tuan
thi phuong » thi truong
trung cua » truong cua, trung cap, dung cua
chi sach » chinh sach, chieu sach, co sach
dan than » dan chan, ban than, van than
van tuan » van quan, van ban, anh tuan
doi chi » doi khi

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: doi chi sach - thanh ((trung cua) OR (trung tuan)) thi phuong ((dan than) OR (van tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi sach - thanh ((trung cua) OR (trung tuan)) thi phuong ((dan than) or (van tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi chi sach - thanh ((trung cua) OR (trung tuan)) thi phuong ((dan than) or (van tuan)) cau*.
