Trong cuộc đời và sự nghiệp văn học, Nguyễn Trãi đã dành trọn tâm huyết cho dân như thế nào? 

Rồi hóng mát thuở ngày trường,
Hoè lục đùn đùn tán rợp giương.
Thạch lựu hiên còn phun thức đỏ,
Hồng liên trì đã tiễn mùi hương.

Dắng dỏi cầm ve lầu tịch dương.
Dẽ có Ngu cầm đàn một tiếng,
Dân giàu đủ khắp đòi phương.
