Hunan cuisine was not very spicy at first, but it was unbearable in the later stage.

Haha, that's not all. What you said is that some peppers have enough stamina, which is acceptable at first, but they can't stand it after eating them, such as autumn peppers, which are particularly spicy and have enough stamina. People in Hunan often eat spicy food. They are used to it. If you don't eat much, enough is enough. Eating too spicy food is bad for your stomach.
