The First Sycophant in Zhenguan

When Chen Du traveled to the Tang Dynasty, he was squatting on death row waiting to be beheaded. He is an old member of the East Palace and a close minister of the prince. After the Xuanwu Gate Incident, Li Shimin was purging their group of people all over the world. Seeing that the knife was about to fall on his neck, Chen Du said to the interrogator: "I want to see the emperor." No one thought he would survive.

All civil and military officials in the dynasty went crazy. A remnant of the former prince, why?
