The late spring rain woven diagonally, making the bluestone road shiny. Su Wan held a faded blue cloth umbrella and stopped in front of the third used bookstore at the entrance of the alley. The four words "Shiguang Bookstore" on the wooden signboard have been softened by the years. The copper bell hanging under the eaves swayed gently with the wind, and the tinkling sound dispelled the dullness of the rainy day.
