Perhaps you should try some spelling variations:
thanh truong » thanh trung, thanh thuong, thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
truong ung » tuong ung, truong trung, truong chung
hoc chieu » hoc thieu, ho chieu, hoc hien
cong tran » cong tan, cong tuan, cong toan
cong hoan » cong hoa, dong hoa, cong san

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