Our home is near Henan Agricultural University, and there is fresh milk for sale in the relatives' hospital of Agricultural University at about 6 pm every day (if you go late, you can't buy it), which is supplied by the Animal Husbandry and Veterinary Science and Technology Company of Henan Agricultural University (Dongfeng Road has a base), so it should be more secure. It tastes lighter than milk powder, but it feels natural. My family just started drinking, but some neighbors and friends have been making up for a long time. I think this should be more reliable and meet the requirements of the landlord.
