A New Biography of a Family with Children Growing up in Jiangbei

I traveled back in time to Jiangbei, where I had a son and a daughter who were just growing up. But I can't play music and I don't know how to play music. With a system, I can only look up things on the previous earth, but I don't know music symbols, so I can only start writing novels. . . . This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
