Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, hang cong
thanh sang » thanh san, thanh hang, thanh hoang
hanh tang » hanh trang, anh tang, hanh mang
tang cuoc » tang cuong, trong cuoc, tranh cuoc
ho chieu » theo chieu, hoc thieu, mot chieu
sang ban » hang ban, nang ban, sang bae

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 sach - hanh tang cuoc ((nhung cong) OR (dung trong)) thanh sang ban~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh tang cuoc ((nhung cong) or (dung trong)) thanh sang ban*.
