Discrimination between Chinese and foreigners in Song Dynasty

After the death of the Song Dynasty, the standard of "distinguishing between Chinese and foreigners" developed from the stage of blood relationship and ritual patriarchal culture to the stage of simple cultural standard or geographical standard, with more emphasis on "the foreigners entered China, which was called China" and "the foreigners entered China, which was called China". The actual situation is that after the pre-Qin period, the idea of "distinguishing between Chinese and foreigners", which is dominated by cultural factors and measured by blood relationship and region, generally only took a slight dominant position when China faced a serious threat, that is, it suffered a serious invasion and disaster, and this was mainly to protect Chinese civilization and dignity.

Hao Jing, who was born under the rule of the Jurchen nationality, put forward that "if he can be a scholar today and can do the way of China, he will be the Lord of China" (Book of Song Huaiyue, Volume 37).

Hao Jing Volume XIX "On the Official Seal": When the Han Dynasty died, heaven and earth were meaningless and there was no all-rounder in the world. In the Jin Dynasty, ... caused a battle of Yi Di, but the legacy of the Han Dynasty was exhausted, and Huaxia died. Is it necessary for China people to govern well in the future? The sage said,' If you enter China, you will be in China'. Kindness can also be used for reference. Why in China? Hao Jing broke the racial boundaries as the "Lord of China", which provided a theoretical basis for Yidi to rule China.

1260, after Kublai Khan ascended the throne, Hao Jing was appointed as the ambassador of Mongolia to the Southern Song Dynasty, urging the rulers of the Southern Song Dynasty to recognize the legal status of Mongolia as the "Lord of China" and "trust and mend fences" with it. It is in this situation that he put forward the idea that "today's scholars can use it, but if they can do the way of China, they will be the master of China".
