This article can be regarded as a textual research time travel article, but I am not a history or literature major, I am an engineering student, so if there are any errors, please help point them out and I will try my best to correct them within the scope of the plot. Lin Yan is a modern agricultural technician who is terminally ill and travels back to the prosperous Tang Dynasty in the tenth year of Tianbao. He wanted to save the empire. It started from Dunhuang agricultural technology promotion and went all the way east to Chang'an. He was beaten with a cane for thirty years in public in the Western Market. He suffered such a heavy blow that he never recovered from his fall. Policies cannot be delivered, and powerful people cannot gain connections. Everyone in the court knew that An Lushan wanted to rebel, but the interests were so intertwined that no one dared to move. He recognized the reality: he was a time traveler and the protagonist, but at the same time he was also a speck of dust in history. No monument or name. Thousands of years later, cultural relics were unearthed one after another. To this day, no one knows that man saw everything.
