Zhang Youde, the Factory Doctor of the Siheyuan

"Yi Zhonghai, you can't just think about yourself!" "Liu Haizhong, I can recommend you to Deputy Director Li." "Yan Bugui, this bonus could have been given to you..." "Qin Huairu, you don't want Bangge to be expelled from school, right?" "Deaf old lady, do you want me to tell you this secret or not?" … Zhang Youde, who has read 100 Siheyuan novels, traveled back in time to the 1960s to work as a factory doctor in a steel rolling mill, and watched how he used the strategy of "driving tigers and devouring wolves, sowing discord, and intimidation and inducement" to win back the birds! Zhang Youde, the little kid from the courtyard house, eventually became the leader of the steel rolling mill and the grand master of the courtyard house, creating a "warm and happy" courtyard house.
