Tonight, I boarded the K5305 sleeper green leather train, a train-themed hotel. Most of the objects were furnished in the style of the last century, and I felt back to the time of the bridge. The development of the era, the high-speed rail replaced the green-skin train, the speed is improving, the hardware is also improving, or a large number of people yearn for the past green-green train, carrying many years of never-ending. Old car with a swinging fan on the top of the head, the window can be pulled open, and people sit very casually. We have to open 3-4 hours from Hangzhou to Shanghai. Often we are late, we don't care. The days before were very slow, and the horses and horses were very slow. For those who are old, train fans are very recommended to feel some, recall the lush years of that time.
