Siheyuan: Picking up the Dying Sister at the Beginning

Lin Yi, a doctor of science and engineering, travels back to a rural young man who has a poor family and a critically ill eight-year-old sister. He used alum to purify water and cool down physically to regain a glimmer of life in a desperate situation. In order to bring his sister to the city to survive, he burned pottery in exchange for tickets, outsmarted the letter of introduction, and broke into the strictly regulated courtyard house. Since then, knowledge has become the sharpest weapon - from improving production to avoiding storms, from breaking the ice with technology to serving the country through industry. During thirty years of ups and downs, he not only protected his sister, but also ignited the fire of reason and hope for a compound and a country in the tide of the times.
