His shop is called "Lu Ji Antiques" and is located on a street called "Tongluo Lane" in the old city. Tongluo Alley is not long, only three to four hundred meters from beginning to end, but it is lined with antique shops, second-hand bookstores and handicraft workshops. There is an old locust tree at the entrance of the alley. In summer, the locust flowers will fall all over the ground. They are white and make a rustling sound when you step on them.
