Fan Yugan's despicable appearance makes one want to hit him, yet unable to, which almost made the Minister of Revenue of the Yan Kingdom, who is of upright character, faint from anger.
It's said that when a scholar meets a soldier, reasoning becomes futile. This time, coming to Zhou... the Minister of Revenue of the Yan Kingdom truly experienced that when a scholar meets a shameless yet talented soldier, reasoning indeed becomes futile.
Bai Qingyan also understood after reading the records of the negotiations between the two countries sent by the eunuch from Honglu Temple, why Liu Rushi needed Fan Yugan. Besides sympathizing with Fan Yugan himself, it was probably because Fan Yugan, compared to scholars who pride themselves as gentlemen, has a thicker skin. This is not intended to belittle Fan Yugan, but during the haggling between the two countries, someone like Fan Yugan, who can set aside dignity and pride, can indeed make the opponent so angry they lose their composure.
