During the Northern and Southern Dynasties, the white-robed general Chen Qingzhi led 7,000 cavalry in the Northern Expedition to the Central Plains. He conquered 47 cities and 32% of the city, and once conquered Luoyang. However, his success ultimately failed due to the suspicion of the court and the lack of reinforcements. He left behind the historical legend that "famous teachers and generals will not stay in prison, and thousands of troops will avoid white robes".
