I am Jia Dongjin in the Siheyuan (Courtyard House)

An electrician is transported back to a parallel world of a traditional courtyard house, experiencing an ordinary life. Through hard work, he tenaciously survives the tides of history, changing his family's tragic fate. He bravely faces challenges, exploring love, career, education, speculation, and even the true meaning of life. ---Whether under the scorching sun or in the biting cold, I still find joy in it!
