The can of Wangzai milk is marked as reconstituted milk. Reduced milk, also known as "reduced milk" or "reduced milk", means that milk is concentrated and dried into concentrated milk or milk powder, and then an appropriate amount of water is added to make an emulsion with the ratio of water to solids in raw milk.

Generally speaking, reduced milk is reduced milk blended with milk powder, so Wangzai milk is very popular so far.
