Objectively speaking, there are only tea teachers in the large-scale formal milk tea training center in China. Just look at the website and you will know that the entity diagram is really very technical and powerful. Others are not very professional. Small organizations want to borrow some fame, advertise and make a living. But if they are not skilled and professional enough, even if the price is low, it is not an ideal choice, because entrepreneurs who open tea shops spend tens of thousands of dollars to open stores, all of which are hard-earned money. How can they trust unprofessional institutions in order to save two or three hundred dollars? Will the quality of teaching be guaranteed by then? Is technology guaranteed? Worry about penny wise and pound foolish, entrepreneur, you should think twice.
