1, USB small fan: Although it can only be used in summer, the use time is limited, but when there is no air conditioning, such as university classrooms or when traveling, there is a small fan at this time, just like 999! Cool and sweet!

2, juicer: Because I personally don't use juicer very much, but I think it is very practical and indispensable in life. Go home and squeeze a cup of watermelon juice when it is very hot, or squeeze a cup of health tea when you are in good health. How comfortable it is, I feel that the whole standard of living has come up.
