In Paris, I didn't go to the fragrance Museum of fragrance in ten miles. Instead, I took a rain trip all the way through my friends and went to the sewer museum hidden by Senna river. The sewage is running under my feet. The smell is the smell of sewage. I feel so sorry for my friends. But I think I'm familiar with it. It's not like this to see the underground corridor project site. But people's underground corridor took shape nearly two hundred years ago, and it was very mature one hundred years ago. And we just spread it out. Suddenly, I am very confident in GDP. Our investment in infrastructure is promising, because many things can be developed, besides PPP underground pipelines, there are also subway. At the moment, I'm not necessarily crowded on Line 4, because there's only one way to get home, but Paris, Tokyo, there are many choices for the subway line to go home. Beijing's subway network is formed in China, but the network is not close enough.
