Perhaps you should try some spelling variations:
thanh thuong » thanh huong, thanh chuong, thanh phuong
chieu xanh » chieu sach, chieu sang, chieu tinh
thuong ung » thuong dung, thuong hung, huong ung
hoc chieu » hoc thieu, ho chieu, hoc hien
cong tran » cong tan, cong tuan, cong tren
cong toan » cong tan, cong hoan, cong tuan
nhan tu » nhanh tu, phan tu, nhan su

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 chieu xanh - thanh thuong ung dung ((cong tran) OR (cong toan)) nhan tu~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - thanh thuong ung dung ((cong tran) or (cong toan)) nhan tu*.
