Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
nhiet nang » nhiet dong, viet nang, nhieu tang
trung tuan » trung thanh, trung tam, tran tuan
trung tan » trung tran, trung tang, truong tan
trong ban » trong san, trong tan, trong quan
ban than » ban thanh, van thanh, ban hang
than cau » toan cau, phan cau, than cap

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 ((chieu tinh) OR (nhiet nang)) - thanh ((trung tan) OR (trung tuan)) dung trong ban than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (nhiet nang)) - thanh ((trung tan) OR (trung tuan)) dung trong ban than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (nhiet nang)) - thanh ((trung tan) OR (trung tuan)) dung trong ban than cau*.
