In 490 AD, after the death of Feng Taihou, Emperor Xiaowen took over the political power and continued the reform. In 494 (the eighteenth year of Taihe), the capital was moved from Pingcheng to Luoyang, which changed the situation of remote control in the Central Plains in the past and was conducive to ruling the whole country. It also got rid of the bondage and interference of the conservative forces of Xianbei nobles formed in Pingcheng for more than 100 years, which is conducive to continuing reform. Although moving the capital itself does not belong to the system reform, it is an important link in the overall work of Emperor Xiaowen's reform. After Emperor Xiaowen moved to Luoyang, he began the second stage of reform. The focus of the reform is to change the original living customs of Xianbei people and promote Xianbei people to actively accept Chinese culture. The main contents are as follows: 1. Yi Xianbei's clothing is Hanfu-In 4951February, when Emperor Xiaowen received the minister in the first hall, "the class gave him a crown suit", which was the concrete implementation of Yi Xianbei's official clothing as Hanfu. Second, it is stipulated that the imperial court should use Chinese, and Xianbei language is forbidden-Xianbei language is called "Northern Language" and Chinese is called "Sound". Emperor Xiaowen said, "If you want to break the northern dialects today, you must listen to the correct pronunciation." Xianbei officials over the age of 30 should gradually speak Chinese in court. Xianbei officials under the age of 30 should immediately speak Chinese in court. Anyone who deliberately speaks Xianbei language will be demoted and dismissed from office. Third, Xianbei people who moved to Luoyang took Luoyang as their native place and were not allowed to be buried in Pingcheng after their death. Fourth, change the surname of Han and determine the family level-change the original surname of Xianbei nobles to Han. The changed Han surname shall be based on the surname with similar pronunciation to the original Xianbei surname. Tuoba family, headed by yuanshi county County, is the highest family. Qiu Muling's surname is Mu, Bu Liugu's surname is Lu, He Lai's surname is He, Du Gu's surname is Liu, He Lou's surname is Lou, Yu Yu's surname is Yu, Ji Ji's surname is Wei. Big noble's social status is the same as that of Cui, Lu and Wei, the highest families of Han nationality in the north. The surnames of other lower-class aristocrats were also changed to Han surnames, which were equivalent to ordinary gentry of Han nationality. Emperor Xiaowen also managed to make the royal family and Xianbei nobles intermarry with the main gentry of the Han nationality, which was an honor.
