One night, I got on a tram which is different from usual. The light inside the tram were particularly dim and nostalgic. The stairs are placed on the left side of the car body, and there was a "self-closing position". On the way up, there are rows of rattan chairs filled with souls. This is "No.120", which is similar to the style of 1949 tram. As every tram has no fixed frequency and route, No.120 is a unique space that can only be met. Once you set foot on it, it's like going back to the last century. Passengers are like adventurers. They must grasp the journey, explore and unlock every detail in the car. I met No.120 several times later. Obviously there was no need to take a bus, but people want to get on the bus again and admire its beauty.
