Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, nhung don
chieu tinh » trieu tinh, lieu tinh, kieu tinh
chau tinh » cuu tinh, ha tinh, cua tinh
kinh doan » kinh doanh, minh doan, thinh doan
hang cong » dang cong, hang nong, bang cong
vang toan » van toan, dang toan, quang 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: doi ((chieu tinh) OR (chau tinh)) - kinh doan va ((nhung cong) OR (hang cong)) vang toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) or (chau tinh)) - kinh doan va ((nhung cong) OR (hang cong)) vang toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) or (chau tinh)) - kinh doan va ((nhung cong) OR (hang cong)) vang toan ban*.
