Yang Zhao
In 606, Yang Zhao went to Luoyang to greet his parents, and he spent several months there. He requested permission to remain longer at Luoyang, but Emperor Yang denied it. Meanwhile, because he was required to kneel before his father and had to do so repeatedly while at Luoyang, and he was severely overweight, he became ill from the fatigue, and he died in summer 606. When his son Yang Tong later took the throne in 618 during the dynasty's disintegration, he was posthumously honored as an emperor.
