When did Britain establish the feudal system?

Iberians, cyclists and Celts from the Mediterranean came to England in BC. 1-In the 5th century, the southeast of Great Britain was ruled by the Roman Empire. After the Romans retreated, the Angles, Saxons and Jutes in Northern Europe invaded and settled in succession. The feudal system began to form in the 7th century, and many small countries merged into seven kingdoms, contending for hegemony for 200 years, which is known as the "Anglo-Saxon era". In 829, King Egbert of Wessex unified England. It was invaded by the Danes at the end of the 8th century, and from 10 16 to 1042, it was a part of the Danish pirate empire. The Duke of Normandy crossed the sea to conquer England in 1066 after the short-term rule of the English king. 12 15 King John was forced to sign the Magna Carta and his kingship was suppressed. From 1338 to 1453, Britain and France fought a "hundred-year war", and Britain won first and then lost. 1536 Wales was incorporated into England. 1588 defeated the Spanish "Armada" and established maritime hegemony. 1640, Britain was the first bourgeois revolution in the world and became the pioneer of bourgeois revolution. 1May 649 19, the Republic of China was proclaimed. 1660 restored the dynasty, 1688 witnessed a "glorious revolution" and established a constitutional monarchy.

So Britain should have formed a feudal system in the 7th century. At this time, China was in the Sui and Tang Dynasties (58 1-907).
