In the face of foreign invasion and regime change, what will the duke of Confucius' offspring feast do?

As we all know, the Confucius family, the first hereditary family in the history of China, regarded Confucius as a saint in ancient China. Then why did the Duke of Feast, the direct descendant of Confucius, not organize to resist when the foreign invaders invaded, but immediately and quickly surrendered to the foreign invaders and asked them to continue the title of "Duke of Feast"?

1. After the demise of the Northern Song Dynasty, Song Gaozong led 100 officials south and moved the capital to Lin 'an. Three years after the proposal, Confucius' forty-eighth grandson, Duke Kong Duanyou of Feast, was called to move south. Yan, Meng, Zeng, etc. 100 people, and chartered a boat from Guazhou to cross the river, and escorted the treasure to Lin 'an in mid-February. On February 18, Kong Duanyou made a pilgrimage to Song Gaozong. Please give him a temple house and resettle a large number of immigrants to Kuili. Song Gaozong presented Quzhou Confucius Temple. History calls it "crossing south in a hurry", also known as "crossing south in batches".

2, the sage's learning, early spread to the world. The study of saints is an official study and a study of saints, which cannot be equated with the disciples of Confucius' private school in Shandong. Understand that saints have their own teachers. Although the attitude of the feast duke is symbolic, it has no substantive guiding role. This can be seen from the performance of adherents in the early Qing Dynasty. This supports what I said above from one side.

3, the world changed hands, and the emperor dominated the summer, which changed greatly. Change, dry Kun's reason. Tiande has no head and no constant head; Kang long has regrets, and Yang Jiang is old. Gan Kun turns, heaven and earth are mysterious, if you don't do it, you will be closed, Thailand will be open, the sky will remain the same, and the Tao will remain the same. The five virtues will always be the people who entered our country, my people, and my civilization is gone!

4. Confucian family's continuation of feudal ethics is the mainstream thought of past dynasties. No matter which regime, attaching importance to Confucian ethics is a manifestation of "conforming to heaven". The Kongs have never been radical, but are the upper class of non-royalty. As a link, conforming to the new regime can be said to lead people to obey, which will indirectly speed up the transition of the regime and reduce social unrest, which is in line with Confucianism.
