There is also the fact that the fire in Zhenzong Fanzhen was actually Xujiahuo. Two brothers and two brothers, the old man died and the brothers separated, all took over this craft, and the quality was excellent.
Later, when I left Fanzhen, I passed by and saw a big sign of "intangible cultural heritage" on the street, only to know that it had been industrialized and marketized. I bought a few, but they were much smaller. I hit more sesame seeds. I'll eat it while it's hot, but it's not bad when it's cold. There is one person and two accompanying persons. I remember it was like three or four dollars each.
If you want to learn this craft, you can look at the billboard on the street with the phone number of joining, or go to Fanzhen in person, make a field trip and chat with Erxu.
I'm not in this line of work, so I can't give you more direct help, but I know something, and I hope to give you some reference!
When doing business, don't forget to invite your buddy to have a fire. It smells good!
