Zhang Heng's Return to Tianfu (60 words)
Going to the capital is permanent, and ignorance is used to assist;
When I was in Linchuan, I wanted to find a fish. Once the river was clear, it was not due.
Feeling Cai Zi's generosity, I suspect it comes from Tang Sheng.
I dare to chase the fisherman and play with him.
It's been a long time since I left the world.
