Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
trinh xuat » trinh luat, trinh xuan, trich xuat
doi chieu » doc hieu, doi chi, ho chieu
trinh cua » trinh luat, trinh quan, trinh luan
dung cong » dung trong
cong nang » cong ngang, cong lang, cong nong
nang sang » nang song, nong san
tinh cua » sinh cua, tinh chat, tranh cua
sang cu » sang cua, dang cu, sang tu

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 sach - hanh ((((trinh cua) OR (trinh xuat))) OR (tinh cua)) dung cong nang sang cu~.
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh ((((trinh cua) or (trinh xuat))) or (tinh cua)) dung cong nang sang cu*.
