Why are people in Henan called pepper and qinjiao?

There are two main reasons why people in Henan call pepper Qin pepper.

First of all, Qinjiao is a variety of pepper, and its name comes from its production in Qindi, Shaanxi. The climate, soil and environment in Henan are very suitable for the growth of pepper. Therefore, Qin pepper is widely planted in Henan, and is called "Qin pepper".

Secondly, it may be related to the folklore that Henan people call pepper Qin pepper. It is said that after Qin Gui betrayed his country and Yue Fei was killed by traitors, people hated Qin Gui. An old man in Lu Yi shouted "Qin pepper, Qin pepper, poisonous Qin pepper" in the street, which attracted many people to talk about it and came to buy it. After a long time, the name "Qinjiao" was widely circulated and became the common name of Henan pepper.
