After Emperor Wendi of Sui Dynasty unified China, he practiced frugality and took many measures to consolidate the political power. Because he realized that "since ancient times, emperors have been able to support the elderly without luxury", he began to advocate frugality in life, and the concubines in the palace did not make beautiful decorations. Generally, literati use cloth and silk, and ribbons only use bronze and iron horns instead of gold and jade. Wendi tried to use beard powder and knitted collar, but he looked everywhere in the palace and couldn't find it. This frugal practice correspondingly lightens the burden on the people and is conducive to the implementation of various measures.

The Northern Wei Dynasty (386 ~ 557) was a feudal dynasty established by Tuoba GUI, a Xianbei nationality. It was the first dynasty in the Northern Dynasties during the Southern and Northern Dynasties, also known as Tuoba GUI and Wei Yuan. In 385, the former Qin Dynasty was divided, and Tuoba GUI became king in Niuchuan, rebuilding the country and making its capital Lesheng (now Hohhot and Linger County, Inner Mongolia). In 386, the country name was changed to "Wei", which was called "Northern Wei" in history. In 398, Tuoba GUI, Emperor Daowu, moved the capital to Pingcheng (now Datong City, Shanxi Province). In 439, Emperor Tuoba Tao unified the north. In 493, Emperor Xiaowen Tuoba Hong moved to Luoyang to carry out large-scale reforms. In 534, it was divided into Eastern Wei and Western Wei. In the eighth year of Wuding in the Eastern Wei Dynasty (550), Levin abolished filial piety and appointed emperor, representing the independence of the Eastern Wei Dynasty and the establishment of the Northern Qi Dynasty. In 557, Zen was located in Yuwenjue, which established the Northern Zhou Dynasty and ended the history of the Northern Wei Dynasty. From 386 when Tuoba GUI, Emperor Daowu, rebuilt the country to 534, the Northern Wei Dynasty experienced 20 emperors, totaling 1.48 years. During the Northern Wei Dynasty, Buddhism rose, developed unprecedentedly, moved the capital to Luoyang, and changed customs, which promoted the feudalization and national integration of the Northern Wei Dynasty.
