Why is there a special price for Yili Mengniu pure milk recently? Is there something wrong with the milk?

In June, July and August every year, dairy cows enter the peak period of milk production, but their consumption decreases. All dairy manufacturers have to cut prices and engage in activities to stimulate consumption. The main reason is that people in China are used to giving milk as a gift. There are basically no solar terms in this season, and gifts are rarely given. Activities should be held to stimulate people's consumption. This year, people may stop consuming milk in advance due to the early batch listing of fruits and the low price, and at the same time, due to the Sanlu incident, which led to the milk sales of various manufacturers being blocked and entering the off-season promotion stage in advance.
