Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
canh doanh » hanh doanh, chinh doanh, doanh doanh
nhung cong » dung cong, thong cong, hang cong
chau tinh » cuu tinh, ha tinh, cua tinh
doanh cua » doanh luan
manh toan » thanh toan, anh tuan, tinh toan
toan cao » toan ban, toan tap

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: hoc ((chieu tinh) OR (chau tinh)) - canh doanh cua ((nhung cong) OR (dung trong)) manh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu tinh) OR (chau tinh)) - canh doanh cua ((nhung cong) or (dung trong)) manh toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu tinh) OR (chau tinh)) - canh doanh cua ((nhung cong) or (dung trong)) manh toan cao*.
