Secret: Drink goji berry water. Li Qingyun was born in 1677 and died in 1933, having lived for 256 years. He was a scholar of traditional Chinese medicine and herbal medicine in the late Qing Dynasty and early Republic of China period, and was also a well-known long-lived person in the world. At the age of 100 (1777), he was awarded a special prize by the government for his outstanding achievements in traditional Chinese medicine. At the age of 200, he still often went to universities to give lectures. During this period, he received visits from many Western scholars. Li Qingyun married 24 wives in his lifetime and had many descendants. He believes there are three reasons for his good health and long life: first, he has been a vegetarian for a long time; second, he keeps his mind calm and cheerful; third, he drinks water boiled with goji berries as tea all year round. After hearing the news, medical researchers from the UK and France conducted in-depth studies on the jujube. They discovered that wolfberries contain a vitamin they had never seen before and named it "Vitamin X". It is also called "anti-aging vitamin". Animal experiments have confirmed that Lycium barbarum has the functions of inhibiting the accumulation of fat in fibers, promoting the regeneration of liver cells, lowering blood sugar and cholesterol. The "rejuvenation" effect of Lycium barbarum is manifested as follows: it can stimulate the sex glands and endocrine glands, enhance the secretion of hormones, strengthen the physiological functions of brain cells and nerve cells, prevent the accumulation of toxins in the blood as people age, and thus maintain the normal functions of various tissues in the body.
