Where is Kuaizi County? Was there originally a county in Jiangxi called Kuaizi County?

There was no Kuaizi County in Jiangxi in the past. I guess you heard it wrong or misrepresented it; I guess you are asking about Chopstick Alley. In the past, it generally referred to the distribution center for bamboo product craftsmen. In many provinces in Jiangxi Province There are chopstick alleys in the city, and they are also found in many places across the country; but many immigrants from Jiangxi mostly come from the chopstick alleys in Nanchang, because they all have a custom: using chopsticks to insert meat or pig heads when worshiping their ancestors; of course, just by retaining With this custom, it is difficult to determine that those people are from Chopstick Lane in Nanchang, because there are many places in Jiangxi Province that also have Chopstick Lane and such customs. However, Nanchang used to be a larger city with more residents, which led to out-migration. Most of the people are from Nanchang, not from other places. I myself moved here from Jiangxi and still retain this custom, but I am not sure whether I came from Nanchang or other surrounding cities and counties (such as Poyang, Fuzhou, Yugan, etc.).
