First of all, if you want to go not too far, go around Huijin, where you can eat and drink. It is not difficult for a person to find a quiet place, because there are bound to be many classmates or people he knows along the way.
Secondly, farther away, you can take a bus to RT Mart, Baodai West Road, go to the supermarket, buy some food, go to Shimao Cinema to see a movie, and come back by bus before 9 pm.
Or, if you don't get carsick, you can take bus 305 or 309 to Guanqian Street. "When you look back, that man is watching Qianjie." Xin Qiji wrote this sentence in Guanqian Street, Suzhou Commercial Center. It is suggested that you can cross Niujiaxiang and go to Pingjiang Road for a walk. Only when you leave Suzhou will you know how beautiful the lights in Pingjiang are. I often visit two old bookstores in Niujiaxiang, Literature Mountain House and Shifang Bookstore, both of which are very distinctive bookstores in Suzhou. These landscapes and cultures are enough for you to understand for four years.
It's almost a year since I graduated, and I didn't know why Yu Xin "mourned Jiangnan" until I left Suzhou. Cherish your time, young man.
I wish you happiness!
