Perhaps you should try some spelling variations:
chieu tach » chieu sach, chiu trach, chieu tinh
chiet tach » chieu sach
tong huong » thong huong, tong thuong, cong huong
doan phan » doanh phan, toan phan, doanh nhan
dan phan » dan chan, van phan, dam phan
cong cu » chung cu
cu tong » cuu tong, cua tong, tu tong

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 tach) OR (chiet tach)) - thanh cong cu tong huong ((dan phan) OR (doan phan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tach) or (chiet tach)) - thanh cong cu tong huong ((dan phan) OR (doan phan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tach) or (chiet tach)) - thanh cong cu tong huong ((dan phan) OR (doan phan)) cau*.
