The Sword Saint said he didn't recognize this old man, and Zheng Fan believed him, because there were indeed too many with the surname Yu, and the Sword Saint and his brother's family were very poor at the time. Although nominally of noble lineage, they were no different from ordinary people. Besides, the treatment of the Emperor Jin at that time was poor as well, limited to just the capital city.
The Sword Saint himself harbored animosity towards the Emperor Jin and did not take pride in his surname Yu, considering it a shame. Even after gaining fame, he disdained engaging with those of the Yu clan.
Therefore, this old man might well be one of the few Yu clan aristocrats who refused to accompany the Emperor Jin to Yanjing, abandoning a life of luxury and splendor to fall into such a state. Truly hard-hearted, akin to the old saying "preferring to die of hunger than to eat Zhou grain."
