Five years have passed, and the old street, which carries the joys and sorrows of several generations, has been reborn and has been selected as a historical and cultural district. One spring afternoon, Chen Hai, an architectural conservation expert, welcomed the third and fourth generations of the Zheng family who had returned from Taiwan to seek their roots under the old jujube tree in Courtyard No. 17. The Old Street Memory Museum displays family letters across the Taiwan Strait, and the grandson of a former opponent has become a new cultural star. When Chen Hai received an overseas call from his son to choose a major in heritage protection, he was pleased to see that the seeds of inheritance had taken root. The Lantern Festival under night witnessed the miracle of the old street's transformation from the brink of disappearance to the rebirth of prosperity. This is a story about return, inheritance and hope, revealing that the real vicissitudes of life lie in the human heart, and as long as feelings last and memories last, the song of time will never stop.
