Life is more than medlar, it is a mockery of middle-aged and elderly people. Lycium barbarum and thermos cup are both health preservation. When people reach middle-aged thermos cups, Lycium barbarum can't stop the years. This word comes from an adaptation of a song. The original words are that life is not just the present, but also poetry and distance. Gao wrote and composed, and Xu Wei sang. Some people joked that there is only a thermos cup with medlar between you and the middle-aged crisis. After so many years of rebellion, people guessed this truth in middle age: I smoke, drink and play rock and roll, but I know what I know about health. It seems that the thermos cup and medlar will be the biggest winners.
