It's good to add whole grains to that. There is a health canteen in Daosheng Garden. I don't know if it's ok. Everyone said they made money.
I joined the Daoshengyuan healthy canteen. I used to run a restaurant, but my business is gradually failing. I didn't make much money at first, so I could barely make a living. But after two months, more and more people came, especially the five-grain health porridge series, which was particularly popular and sold out every day. Natural honey is added to the porridge, and the taste is more unique. Join us, although you can't say how much money you can earn, at least you can. I hope I can help you, and I think that's what you want to hear most.
