Hairdresser

When a social science guy traveled through time and became a hairdresser, history was completely shaved off. Zhang Heng, a doctor of chemical engineering who is involved in life and death in modern society, traveled to Beijing in 1894 due to a laboratory accident. When I woke up, I had a razor in my hand, and sitting in front of me was a banner man with a fleshy face - waiting for him to shave. There is no system, no grandfather, and no portable space. The only golden finger is a brain full of physical, chemical and biological knowledge from exam-oriented education and the social animal's desire to survive in the 21st century. I wanted to make a living by shaving my hair, but I accidentally shaved people who shouldn't have been shaved: the frowning Guangxu, the daydreaming Kang Youwei, Sheng Xuanhuai who had "I want to make money" written all over his face, and the old Buddha who shook the back of his head three times when he faced anyone. When the foreigners' powerful ships and cannons knocked on the country's door again, and when the Sino-Japanese War of Sino-Japanese War gathered dark clouds, Zhang Heng found that he was just a little butterfly, and he had to flap his wings to blow up the typhoon. He used sulfur, saltpeter and charcoal to teach the great powers how to behave, used arithmetic sequences to help Li Hongzhang settle accounts, and used microbiological theory to make the Imperial Hospital collectively unemployed. He built factories, published newspapers, trained new troops, and deceived the decadent princes and nobles into stunned silence. This is the late Qing Dynasty, an era of baldness. And he is the best barber in the Qing Dynasty - specializing in treating all kinds of dissatisfaction.
