There is an antique shop called "Echo Shop" in the old town of Linjiang Town. On the surface, it sells old things, but in fact, it secretly sells "memory carriers" that carry the memories of others. "Everything around you may be a memory imprint given by" memory. Those who touch it can pry into the truth, but excessive indulgence in memory imprints can lead to memory disorders. These people are called "Echoers"
