In the old city, I have seen so many joys and sorrows, and seen so many people's dreams and realities. Regarding growth, it has nothing to do with romance or legendary life, it is just the trajectory of people in the old city towards life, the traces of growth in collisions. The flowers bloomed that year, and the streets and alleys were filled with the unique aroma of paulownia trees belonging to the old city. People also entered the trajectory of life in the unique atmosphere of the old city.
