Only when he really arrives at the night of Sixteen Nights can he really realize his great career. And that night was also the real killing night in Luoyang. So, perhaps to remind myself that the killer in the Spring and Autumn Period was called "Izayoi".

At that time, in order to facilitate the rulers to manage and consolidate the political power, the "curfew" system was implemented from the Tang Dynasty. In other words, people can't go out at night. At that time, the yamen would ring 600 closed-door drums every night, and 400 opened-door drums after three o'clock in the morning.
