2. First, the city of central France, the regional capital of the central region and the capital of Loire province, is flat, and the Loire River, the largest river in France, runs through the urban area. Orleans is a new industrial city in France, which belongs to the one-hour economic circle of Paris, and ranks 25th in terms of economic level and city size. It is a typical "people-rich" city.

3. The Loire River, the largest river in France, runs through downtown Orleans, which is the second largest city on the Loire River, second only to Nantes, and neck and neck with Angers and Tours. There are many wetlands along the Loire River, and there is a canal parallel to it on the north bank. Before the railway was opened to traffic, there were many ships on the canal, and the business was prosperous, but it has now been abandoned. The Loire River itself has a low water level, which is not suitable for developing shipping. Besides, expressway and high-grade railways are built in parallel along the Loire River, so Orleans is not a water transport hub. The Loiret River, a tributary of the Loire River, runs through the southern part of the city and joins the Loire River in the western part of the city.

4. Orleans is also a kind of compound marinade or compound spice (with pungent flavor, giving food flavor).
