The chief Cathedral of St. Jean in the old city of Lyon is a typical Gothic building with a history of nearly a thousand years. Without the endless queue of people in Notre Dame, Paris, to enter the church and sit quietly for a while, the restlessness of the heart will naturally calm down in the solemn atmosphere and the background music of the hymn. The glass windows of the church are very beautiful. Every pattern is different. The sunshine shines brightly through them. The photos do not reflect one tenth of the beauty. It was also the place where Pope John 22 was crowned and witnessed the wedding of King Henry IV and Queen Mary. There is a famous astronomical clock in the church, and it is said that it will ring at 12 o'clock on time. The villains inside will come out to dance. Everyone waits and waits until 12:15. There is no such scenic spot. It's a pity.
