The thing Chai Lingwu regretted most in his life was taking another look at his own account book when he was twelve years old.
It can be seen that the loss rate of Luoyang salt is wrong. I saw the price difference between Yangzhou Silk Road and Changan Beiku. I saw a nest of rats that had been hiding in the Chai family business for ten years.
On the day when the eldest brother went to guard the Western Region, he handed over the Chai family to him.
Man Chang'an waited to see the joke made by this prince-in-law.
Three months later, Chai Lingwu placed a clear double-entry account book on the desk of Tian Khan Li Shimin. Li Er flipped through it again and again, and finally asked just one sentence: "Can you teach the Ministry of Household Accounting how to keep accounts?"
Chai Lingwu said, yes.
That was the sixteenth year of Zhenguan. He didn't know yet that these words would make him the sharpest knife in Tian Khan's hand.
Little did he know that one day, he would put this knife on another emperor's neck.
