Wang Chuzhi
Concerned, Wang Chuzhi contacted his son Wang Yu—who was then serving as the military prefect (團練使, "Tuanlianshi") of Xin Prefecture (新州, in modern Zhangjiakou, Hebei) under Li Cunxu. He requested that Wang Yu secretly instigate an incursion by Khitan's Emperor Taizu. Wang Yu agreed, and also requested to be made his heir, and Wang Chuzhi agreed.
