I'm a purchasing agent in Hong Kong, and I also have a physical store in China, but every time I buy, the quantity will not be large. Only a few cans of each kind will be placed in the store, and if the whole case is needed, I will order it, and then I will arrange the delivery, only for quality, not quantity.
As a mother, I can understand the troubles and anxieties caused by the recent milk powder problems. I can't tell the truth from the appearance, but I have different names for different areas. I can't open the can when buying milk powder, try to feel it, smell it and taste it again. You can only find a more honest seller.
