Duan Zhixuan

Duan Xiong (), titled Duke Zhongzhuang of Bao, better known by his courtesy name as Duan Zhixuan (), was a general and officer in early Tang Dynasty. He is one of 24 honored founding officials of Tang Dynasty at Lingyan Pavilion.
In history.
Duan Zhixuan is the son of Duan Yanshi, a mid-low ranked officer of Taiyuan in Sui Dynasty, and a friend to Li Yuan, the founding emperor of Tang Dynasty. Duan Zhixuan and his father joined the rebellion led by Li Yuan that eventually overthrew Sui Dynasty in 617-618. During the rebellion, Duan Zhixuan, Chai Shao and Liu Wenjing defeated and captured the Sui generals Sang Xianhe and Qutu Tong in a battle near Tong Pass. Duan was rewarded the title Marquis of Linji after this battle. Later, he became a subordinate to Li Shimin and took part in unification wars against various warlords including Xue Ju, Liu Wuzhou and Wang Shichong. In 626, he was a key figure that helped Li Shimin obtain the crown in the Xuanwu Gate Incident. When Li Shimin became the emperor (Emperor Taizong of Tang), Duan Zhixuan was rewarded the title Duke of Fan and appointed to be the Grand General of Left Brave Guard. During the reign of Emperor Taizong, Duan Zhixuan served in different positions both in the military and in local government. He also took part in the early stage of the campaign against Tuyuhun in 634. In 637, his title changed to Duke of Bao, and his descendants were given the privilege to inherit his title. He died in 642 and was given a posthumous name Zhongzhuang ().
In popular culture.
In Chinese folklores and some classic novels, Duan Zhixuan is often mistakenly referred to as Duan Zhiyuan () or Duan Zhixian (). In those folk stories, Duan Zhixuan is one of four close guards (along with Ma Sanbao, Liu Hongji and Yin Kaishan) protecting Li Shimin. He was killed by the Korean general Yeon Gaesomun during a war between Tang and Goguryeo.
