Emperor Wu of the Han Dynasty greatly respected his uncle Liu An and appreciated his talent. Every time Liu An has a new book, Emperor Wu of the Han Dynasty will read it all night and then collect it. At first, Liu An didn't want to rebel. He just wants to be his monarch. However, due to the fact that Emperor Wudi had no son at that time and the persuasion of the people, Liu An gradually became disloyal and committed suicide after the defeat.
As a rare wizard in Han Dynasty, Liu An was keen on the technique of Huang Lao, devoted himself to becoming an immortal, recruited all kinds of magicians, and personally participated in refining Dan medicine. It is said that after the failure of the Anshi Rebellion, Emperor Wu of the Han Dynasty sent people to Huainan to arrest Liu An. Without any hesitation, he took the elixir he refined. Besides, before he died, Liu An gave all the pills he hadn't eaten to his dogs and chickens, and both of them died. Therefore, there is an allusion that "one person gets the word, and chickens and dogs ascend to heaven".
According to historical records, Liu An was the first person in the world to study the launch of a hot air balloon. One day, on a whim, Liu An drained the raw eggs, leaving only the eggshell, and then used fuel to provide hot air to make the eggshell float. From the perspective of modern people, Liu An's hot air balloon experiment is very funny, but in the Western Han Dynasty more than 2,000 years ago, it was very commendable and admirable to have such an idea.
Tofu is a common food on the table. Almost everyone likes it, but few people know that its inventor is Liu An. At that time, Huainan was rich in soybeans, so people used soybeans to grind them into pulp and drink them. Liu An also likes to drink soybean milk. On one occasion, Liu An was carrying soybean milk in an alchemy, and accidentally spilled it on the gypsum beside the alchemy furnace.
Liu An didn't care at first, but after the explosion, he found that the liquid soybean milk turned into something soft. If you were someone else, you might not go deep into it, but Liu An tasted it himself and found it delicious, which made him very happy. He immediately brought a large pot of soybean milk, crushed gypsum and stirred it into soybean milk, so he invented tofu. We can eat delicious tofu now, thanks to Liu An, the king of Huainan.
In addition, Liu An's Huai Nan Zi is a masterpiece of Huang Lao's theory, which not only puts forward unique views on Tao, heaven and man, form and spirit, but also puts forward a systematic theory of universe generation on the basis of Huang Lao's theory. I have to say that Liu An is a rare wizard.
Then the problem is coming. Do you like tofu?
