You'd better go to Langzhong for a few days.

I am from Langzhong. I suggest that the ancient city of Langzhong should be a signboard for three days at most, and the Gongyuan Kongjia Courtyard of Zhangfei Temple is all in it. You can finish them in one day. If you don't want to be in a hurry, it's only two days at most, and then you can go to the Buddha Temple in Jinping and stay on the mountain for one day. Other places, such as Tiangongyuan, can be chosen, and some places have not yet developed tourism facilities and services. In fact, many people come to Langzhong for the ancient city.
