If you make your own hot pot, search the Internet for spices. For example, 5g of Amomum tsaoko, 5g of Rhizoma Kaempferiae, 3g of clove, 5g of Amomum villosum, 5g of cumin, 5g of cinnamon, 5g of licorice, 5g of grass, 5g of Laokou, 5g of Gan Song, 5g of dried tangerine peel, 5g of citronella, 8g of star anise, 5g of fragrant leaves, 5g of fennel and 8g of vanilla.
If you want to cook in a restaurant, you can sell hotpot ingredients online.
If you want to open your own hot pot restaurant, I suggest you go to a special hot pot training room to study. Recently, there is a hot pot studio called Zhong Mingyu. You can go and have a look.
I hope it will help you and I hope it will be adopted.
