Ah, across thousands of miles, I finally came to the long-lost Luxembourg. The whole country is like a big forest. There are many castles in the suburbs. We went to the most famous Fianden Castle and saw the castle for the first time. A little excited! I remember the teacher in the history class said that the country is small, but the per capita GDP is very high, and it is the richest in Europe. So I remembered it. After I came, I found that the mountains are good and the water is high... I have a high salary and high prices. I am waiting for tourists... I want to make a small public offering in the old castle.
