What is the biggest change in Suzhou in recent years?

I remember eight years ago, when the school bus pulled us from the railway station to the school headquarters, we saw that the school bus was almost rubbing against the buttonwood trees on the roadside in Shizi Street, but the driver was not nervous at all, and we were safely sent to the front of the chrysanthemum hall. At that time, my first impression of Suzhou was: "Suzhou is so small. Is this the legendary Suzhou with Suzhou and Hangzhou in heaven?" I started my seven-year college life with a thousand miles away from home and a little dissatisfaction. After living in a student apartment on the roadside of Mo Xie for a month during military training, I moved to Su Yi on Wuqieqiao Road. Looking at the narrow campus and the unusual old dormitory, I was impressed by the gap in my heart at that time. At that time, my impression of Suzhou was that there was no urban atmosphere, and the streets were very quiet at eight or nine o'clock at night, with few cars, especially private cars. Gradually, with the understanding of the history of the ancient city, the characteristic buildings, the government's measures to protect the ancient city, many scenic spots, and the tranquility of the night, the feelings for this city are getting deeper and deeper. Because of the concentration of urban attractions, human tricycles can be seen everywhere in the city, which can accommodate one or two people, and there are not many taxis. When I was a freshman, I flew kites in the park. At that time, Jinji Lake was under construction. Later, it became a place where I often went for walks and picnics with my classmates and friends. Now, my friends have settled down by the lake.

and what about Suzhou now? Cars, large and small, are parked on the streets that are not spacious, and the non-motor vehicle lanes are no exception. Riding in the non-motor vehicle lanes, cars turn in from the motor vehicle lanes or come from behind you from time to time, and some don't even honk their horns to remind you; I don't know since when, scooters and tricycles have been jumping around soliciting customers in the street. Together with human tricycles, non-motor vehicle lanes have become more crowded and unsafe. On holidays, Guanqian block is even more crowded, and people or cars may hit you when you walk. The slogan of a real estate developer also reads "Before and after Guanqian, there is no center for Suzhou to walk". Is it bustling or congested?
