Perhaps you should try some spelling variations:
thanh thanh » nhanh thanh, thanh toan, thanh phan
chieu sach » chinh sach, chiet tach, chieu sang
hien xanh » hien hanh, hien nhanh, chieu xanh
va trong » va truong, va tuong, va trung
va thong » va thuong, va phuong, he thong
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cap » khan cap, thanh lap, thanh cac

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 ((hien xanh) OR (chieu sach)) - thanh thanh ((va trong) OR (va thong)) cong tan than cap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (chieu sach)) - thanh thanh ((va trong) or (va thong)) cong tan than cap*.
