How is the quality of yogurt in Le Chun? Where is the milk source? Is it reliable?

I really know this. I have a friend who works in Le Chun. It is said that the milk source currently used in Le Chun is fresh milk from the open-air pasture of Beijing Academy of Agricultural Sciences, which is absolutely guaranteed. At the same time, Le Chun also signed a strategic cooperation agreement with Huaxia Animal Husbandry to adopt the highest standard milk source recognized by the industry. Really make users safe and secure.
