Du Fu's metrical poems in his later years showed extraordinary artistic skill, showing solid and luxurious characteristics.
The poet broke through the more realistic style in his early creation, did not stick to the real life itself, and integrated beautiful rhythm, wonderful ideas, concise poems, gorgeous colors and far-reaching images, sublimated his thoughts and feelings, pursued artistic beauty, and Wang Yang was free and easy. For example, eight poems about autumn and five poems about historic sites are like "bound rockets" to express emotions, all of which are carefully produced, which is unprecedented in previous creations.
It's just that he paid too much attention to social unrest and people's livelihood in his early years. In his later years, he didn't repeat the same mistakes. Instead, he kept his spirit alone and accumulated a lot of money, casting a deeper poetry.
