If there is a street near Chongqing University Town, there are many hot pot restaurants. If you want to be spicy, you can eat some pot-stewed dishes, such as delicious duck neck, mala Tang, skewers and so on. There is a food city near the Agricultural Bank over there, where there are many snacks and everyone has different tastes. You can go there to find something that you think is spicy and delicious.
A little further away is a town in Chen Jiaqiao, where spicy things have to be dug by themselves. Personally, it's all so-so, hehe, I hope to adopt it.
