Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trung » thanh trung, hanh trang, manh trung
trung tuan » trung thanh, trung tam, tran tuan
hieu lang » chieu sang, hieu quang, nhieu tang
tuan hang » tuan hoang, tuan bang, tuan dang
hang cong » dang cong, hang nong, bang cong
cong danh » cuong danh, cong dan, cong thanh

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