Sacrificing pillars in Song Dynasty in Ming Dynasty

I heard that when Yan Song was in power, anyone who paid bribes to Yan Song's family could get Yan Song's name card (similar to a business card). The people in the queue are holding this famous card and want to give Yan's "Chengyi" 3,200 silver. Speaking of this famous post, if you get one, you can avoid being framed by others in court. (To put it bluntly, the person who has this post is Yan's best friend, and court officials are inviolable. ) Mr. Song Maodian, who lives in Sanshan Street, Jinling (Nanjing), also has such a post, which has been kept as an antique collection. It says "white pine". The font is imitation of Lu Gong (calligrapher at that time, whose name was forgotten), and the size is about 5 inches. There are no borders on all four sides of this paper. Forty-five years of Qianlong (1780) I have seen it with my own eyes.
