Generally, there are two channels for purchasing raw materials. You can choose according to your own situation. First of all, we can buy goods on Taobao, which is more convenient. The disadvantage is that the quality of our own goods may be difficult to guarantee and suitable for experienced people. If it is the first time to open a tea shop, I suggest you choose a reliable supplier to cooperate. For example, the milk used in my shop is full flavor, and I use full flavor frozen milk. This milk has a good proportion of protein and fat, full flavor and mellow taste, which is very suitable for making milk tea. In addition, it is convenient to purchase goods in cooperation with Quan Wei, as long as you pay attention to the marketing of foreign food in Quan Wei.
