Does anyone know which company the street lady's bean paste milk belongs to?

I know, generally speaking, Shijingpo bean paste milk is one of the brands operated by Hebei Stafford Catering Management Co., Ltd., which officially started operation on July 15, 2020. Its first store is located in Shijiazhuang, Hebei province? Up to now, there are more than 300 stores in China, which have covered most cities in China. I have tasted every drink in its house, so I don't blindly step on the thunder! ?
