This application introduces these persons who live in three kingdoms of Chinese. The Three Kingdoms period was a period in Chinese history, part of an era of disunity called the "Six Dynasties" following immediately the loss of de facto power of the Han Dynasty rulers. In a strict academic sense, it refers to the period between the foundation of the state of Wei in 220 AD and the conquest of the state of Wu by the Jìn Dynasty in 280. However, many Chinese historians extend the starting point of this period back to various years during the collapse of the Han dynasty, such as to the Yellow Turban Rebellion in 184; the year after the beginning of the rebellion, 185; Dong Zhuo deposing and murdering Emperor Shao of Han and establishing Emperor Xian of Han in 189; Dong Zhuo sacking Luoyang and moving the capital to Chang'an in 190; or Cao Cao placing the emperor under his control in Xuchang in 196.
