One of the six major railway stations in Paris had the idea that every railway station in Paris should be trampled on. Eventually, because of the bad weather, we took ERE from Charles de Gaulle Airport to the North Station of Paris. As a result, the North Station of Paris became the first railway station to arrive in this journey. The North Station of Paris is the first station of the European Star of Paris and one of the busiest railway stations in Paris, and came down ERE. After that, it was a bit hard to get out, too many doors, a little dizzy. Up to the second floor, I found the departure floor of the railway station, and circled for half a day. The map navigation in the station was totally ineffective. After leaving the station, I looked at the facade of the old railway station, full of vicissitudes of life, and the modern city of Paris. This is a good integration.
