Wei Dynasty (魏朝) can refer to two different dynasties in Chinese history:

The Northern Wei Dynasty (Chinese: 北魏朝; pinyin: Běi Wèi Cháo), also known as the Tuoba Wei (拓拔魏), Later Wei (後魏), or Yuan Wei (元魏), was a dynasty which ruled northern China from 386 to 534 (de jure until 535). Described as "part of an era of political turbulence and intense social and cultural change", the Northern Wei Dynasty is particularly noted for unifiying northern China in 439: this was also a period of introduced foreign ideas; such as Buddhism, which became firmly established. Many antiques and art works, both Daoist and Buddhist, from this period have survived. During the Taihe period (477-499) of Emperor Xiaowen, court advisers instituted sweeping reforms and introduced changes that eventually led to the dynasty moving its capital from Datong to Luoyang, in 494. It was the time of the construction of the Buddhist cave sites of Yungang by Datong during the mid-to-late 5th century, and towards the latter part of the dynasty, the Longmen Caves outside the later capital city of Luoyang, in which more than 30,000 Buddhist images from the time of this dynasty have been found. It is thought the dynasty originated from the Tuoba clan of the Xianbei tribe. The Tuoba renamed themselves the Yuan as a part of systematic Sinicization. Towards the end of the dynasty there was significant internal dissension resulting in a split into Eastern Wei Dynasty and Western Wei Dynasty.

Guan Yu (died 219) was a general serving under the warlord Liu Bei during the late Eastern Han Dynasty of China. He played a significant role in the civil war that led to the collapse of the Han Dynasty and the establishment of the state of Shu Han during the Three Kingdoms period, of which Liu Bei was the first emperor.

As one of the best known Chinese historical figures throughout East Asia, Guan's true life stories have largely given way to fictionalized ones, mostly found in the historical novel Romance of the Three Kingdoms or passed down the generations, in which his deeds and moral qualities have been lionized. Guan is respected as an epitome of loyalty and righteousness.

Guan was deified as early as the Sui Dynasty and is still worshipped by many Chinese people today, especially in southern China, Taiwan, and Hong Kong and their descendants overseas. He is a figure in Chinese folk religion, popular Confucianism, Taoism, and Chinese Buddhism, and small shrines to Guan are almost ubiquitous in traditional Chinese shops and restaurants.
