Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu sach » chinh sach, chiet tach, chieu sang
trung tuan » trung thanh, trung tam, tran tuan
lieu tinh » trieu tinh, diep tinh, bien tinh
tuan dung » tuan duong, tran dung, tan dung
cong tac » cong ty
than cap » khan cap, thanh lap, thanh cac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sach) or (lieu tinh)) - thanh trung tuan dung ((cong san) OR (cong tac)) than cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (lieu tinh)) - thanh trung tuan dung ((cong san) OR (cong tac)) than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (lieu tinh)) - thanh trung tuan dung ((cong san) OR (cong tac)) than cap*".
