1. According to Sohu News, the materials are different. Xinshaxian snacks are rich in dishes, and will not be purchased locally for the sake of operating costs. Shaxian snack is a local specialty snack with rich varieties, unique production methods and rich raw materials, and it will use local materials.
2. The establishment time is different. Shaxian snack is the pasta culture of Hakka immigrants 1000 years ago, and the new Shaxian snack was established in 2008.
I hope local people can help me answer this question. When the time comes, I will come to Nanjing and have a drink together.
