It's a little hot to drink milk in summer, but I have a cool way. Put the cold boiled water into an ordinary convenient cup and put it in the refrigerator. It is best to freeze into blocks overnight. Take a cold water cup, add a proper amount of royal jelly (according to your taste), add a little cold water, stir well, add large ice cubes, then pour pure milk into the cold water cup until the ice cubes float, and then you can drink it later. Very cool and sweet, very chilling and no fire! Super cool my unique skills! ! You can have fun!
