When the dragon learned about it, he threatened the castle to offer its daughter as a sacrifice to it. Just when the dragon was about to receive this “sacrifice”, the knight of God, Saint George, suddenly appeared in the name of the Lord, and after a fierce battle , Finally eradicating the extremely ferocious dragon, and at the same time the dragon blood gradually formed a cross shape. The red cross of the British flag comes from here. During the Third Crusade, the Lionheart King Richard I led the army and won the victory at Yakang, which is known as St. George’s Dragon Slaying Ground. The Lionheart believed that it was St. George’s sheltering them. George is considered to be the patron saint of Britain, and St. George’s Cross has also become an important coat of arms and part of the national flag of later generations of Britain. And every April 23rd, “St. George’s Day” has also become an important holiday in England.
