What influence did Emperor Xiaowen's reform have on the development of Xianbei nationality?

1, the positive side: it promoted the feudal process of Xianbei and made the social level of Xianbei develop greatly.

2. On the negative side, it led to the division and opposition between the upper class of Xianbei Sinicization and the conservative lower class, which laid a hidden danger for the later "Six Towns Uprising", brought a hundred years of vendetta and turmoil, and finally led to the complete extinction of Xianbei nationality, which can be described as a sinner of Xianbei nationality.
