A soul from later generations possessed a fifteen-year-old young man in a courtyard house and embarked on an extraordinary journey. Faced with the selfish and bad-behaving "beasts" in the courtyard, he was not afraid and determined to use his wisdom and courage to repair them one by one and restore peace and harmony to the courtyard. At that time, the country's economy was in a difficult stage of development. He was well aware of the historical trend and felt that he had a heavy responsibility. Relying on the knowledge and unique insights of later generations, he resolutely plunged into the wave of the times. Starting from a small courtyard house, he actively contributed his strength in agricultural production, industrial technology innovation, and the popularization of culture and education. With the grand dream of changing history and making the country strong, he took every step firmly and powerfully, just to live up to this journey and leave his own bright chapter in the long river of history.
