Li Siqi
Li Siqi (1323–1374) was a Yuan warlord from Luoshan in Henan who ruled Shaanxi. He raised militia with Chaghan Temur against the Red Turbans, and after clearing Shaanxi of rebels in 1357 built his own power base there. After Chaghan's death in 1362, Li refused orders to obey his son Köke Temür and held Chang'an against Köke's attacks.
He surrendered to the Ming in 1369. The Hongwu Emperor later sent him to win over Köke Temür; Köke's horsemen demanded an arm as a parting gift, and Li Siqi died of the wound in 1374.
