Suo was the slaughterhouse of Wang Lu Palace in Ming Dynasty. It has a history of 300 years. The land here is fertile, and the cultivated tobacco leaves are thick and oily. When they are ripe, fresh tobacco leaves can be picked and dried for a period of time, then burned and smoked. After a long period of drying, they look like jujube paste After burning, it is bright gray and full of fragrance. In the Qing Dynasty, they were paid tribute to the imperial court.
