During the late Eastern Han Dynasty, Li Ying, the Prefect of Henan, was very famous and rarely received guests. There was a 10-year-old boy named Kong Rong, who insisted on meeting Li Ying.

The Prefect's mansion had strict access. Kong Rong told the doorman, 'I am a relative of Lord Li.' The doorman escorted him to meet Li Ying, but Li Ying didn't recognize him and asked, 'What kind of relative are you to me?' Kong Rong replied, 'My ancestor Confucius and your ancestor Laozi had a close friendship. Are we not family friends for generations?'

Li Ying's guests were all astonished to see his quick wit and excellent speaking skills. Only Physician Chen Wei disapproved, saying, 'Clever in childhood, but not necessarily outstanding in adulthood.'

Kong Rong immediately retorted, 'I imagine, sir, you must have been very clear/clever as a child.' This left Chen Wei speechless for quite a while.

After growing up, Kong Rong served as the Administrator of Beihai and other officials, becoming a famous historical figure.
