Du Fu was originally a "rich second generation". When did his life change?

In the fourth year of Tianbao, the Anshi Rebellion broke out. All the assets at home vanished in an instant, so we had to flee to Sichuan. On the way to escape, it is also a luxury to be able to eat. When Du Fu looked at his hungry children on the road, Du Fu, once a rich boy, had no choice but to help. The time of escape made Du Fu.
