Introduction: A college student who stayed up late reading Siheyuan novels traveled through the cold winter of 1949 and became Shen Xinghe, who was begging all the way back to Beijing. He passed out in the alley and was rescued by He Yuyu's soft heart. When he first entered the hospital, he encountered the strange and strange behavior of the third uncle, and the first uncle was suspected of being a spy for no reason. He awakened his savvy and used his golden fingers to match his personal space. He hoarded supplies, acquired top skills in all walks of life, planned the reform and opening up in advance, and broke into a huge industry.
