Story:
During the Eastern Han dynasty, there was a talented scholar named Ying Feng, who possessed an astonishing memory. At the age of twenty, he went to visit Yuan He, an official in Pengcheng.
A carriage maker at Yuan's house opened the door halfway, revealing only half of his face, and told Ying Feng that Yuan He was not home.
Decades later, one day, Ying Feng recognized this carriage maker on the street. The carriage maker was greatly astonished by his memory.
