In the 21st century, He Zilin is an inconspicuous little man in the city, overwhelmed by life. He often sees his own shadow in "Love in the Courtyard". In an accident, he traveled through time and became the silly character He Yuzhu in the drama, and also received a god-level sign-in system. In the courtyard house of the 1960s, he relied on the abilities given by the system to become proficient in music, chess, calligraphy, painting, fighting, and medical skills. He started a business legend and opened a popular medicated food store in the capital. He helped his sister He Yuyu get out of trouble, and also influenced Liu Lan and others to find happiness. He Yuzhu made a counterattack all the way from the ridiculed stupid Zhu to a great genius. More exciting things can be found in "Rebirth of Silly Zhu and Signing to Become the Richest Man".
