Perhaps you should try some spelling variations:
ngang nhanh » nhan nhanh, nganh thanh, nang hanh
chieu sach » chinh sach, chiet tach, chieu sang
thanh hung » thanh huong, thanh tung, thanh trung
nang thanh » dang thanh, tang thanh, nhanh thanh
doi chieu » doc hieu, doi chi, ho chieu
hung tuan » hung tran, quang tuan, trung tuan
tuan dong » tuan duong, quan dong, luan dong
dong cong » duong cong, dung cong, dang cong

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 - thanh hung tuan dong cong ((ngang nhanh) OR (nang thanh)) cau~.
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - thanh hung tuan dong cong ((ngang nhanh) or (nang thanh)) cau*.
