"Flying Light leans his pen to write the heavenly questions, Jin'an's splendid mansion, the thirteen peaks."
The young King Min, Yu Liyang, once roamed the world and wrote this line of poetry, which elevated the thirteen famous mountains within the borders of the Summer Country to the status of being unrivaled.
There is a mountain called Cold Mountain in Jin'an Fu, which is tall and perilously steep, yet it is not listed among the thirteen peaks.
Liu Xiyi, who hails from Jin'an Fu, once said to someone,
"I do not lament that this peak is not tall, but that this peak has not seen Yu Liyang."
In response, Yu Liyang remarked at a banquet, saying, "With Sir Liu Xiyi here, who would dare speak of Cold Mountain?"
Someone asked why he dared not.
Yu Liyang replied, "Fear of a word's slip, leading to a thrashing from Sir Liu!"
It became a widely-known anecdote.
