Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
trung tuan » trung thanh, trung tam, truong thanh
hieu lang » chieu sang, hieu quang, nhieu tang
tran tuan » tran xuan, tran quang, tran thanh
hang cong » dang cong, hang nong, bang cong
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
toan ban » van ban

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: theo ((chieu tinh) OR (hieu lang)) - manh ((trung tuan) OR (tran tuan)) hang cong danh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) or (hieu lang)) - manh ((trung tuan) OR (tran tuan)) hang cong danh toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) or (hieu lang)) - manh ((trung tuan) OR (tran tuan)) hang cong danh toan ban*.
