There is a poem criticizing Yang Guifei and Litchi, written by Su Dongpo, called Litchi Tan. Described the scene of Yang Guifei eating litchi at that time. The poem says: "Flying over the mountains and storks crossing the sea, the wind branches are like new flowers. The beauty in the palace is broken, and the dust is splashed with blood for thousands of years. " Su Dongpo was born in the Song Dynasty, so naturally he didn't see it with his own eyes. These should also be the legends he heard after he arrived in Lingnan. Since it is a legend, there must be feelings in it. I'm afraid it's impossible to prove what the real situation is.
In ancient times, I don't know how litchi was kept fresh, but it is estimated that there should be some preservation methods. Bai Juyi wrote in "Litchi Illustration": If you leave this branch, the color will change one day, the fragrance will change two days, and the taste will change three days. After four or five days, the color, fragrance and taste are gone. So if there is a fresh-keeping method, two days should be no problem. Finally, please correct me. The lychee that Yang Guifei ate should be produced in Sichuan, about 1000 km, and it will arrive in about three days. However, there are still some things that insist that it is produced in Lingnan, no matter where it is produced, such as transporting litchi. Although Su Min hurts money, isn't what royalty does a waste of people and money?
Now let's discuss a problem of shocking dust and spilling blood. Riding a horse must take the post road. Why is someone waiting there to shake the dust and spill blood? Why don't you go away? And it's the first time. I think everyone knows that litchi will be shipped at this time. You shouldn't be so careless, so don't hide it. Anyway, there shouldn't be too many poor people on the postal route, right? Are there many businessmen?
So, I think there is a problem. Since it is not so difficult to transport litchi, and "shocking dust and spilling blood" is obviously a hypothesis, what caused Yang Guifei to fall into eternal infamy because she ate a litchi? Some people will say that people were poor in those days, but no matter how poor they are, they will not be poor in the royal family. I estimate that Yang Guifei's spending money at will will not be worse than litchi, nor will other dynasties.
Because this thing is too elegant? But if you want a litchi, isn't it good to go there? Luckily, she just shipped it out. What if Tang is encouraged to go to Lingnan with her? Isn't there a legend that Emperor Qianlong visited Jiangnan six times for some incredible reasons? Where is Emperor Yang Di? ...
