Shanghai is the main hall, and the people coming and going are screened, but there are also many people whose pace is a little slower than that of Shenzhen. As soon as you enter the door, you can see that the main hall is well decorated, and you are a little tired to welcome guests, so people living in Shanghai have developed the habit of being polite and bargaining with others.
Suzhou is a rare appreciated guest in the back garden, so you can take it for a stroll. The pace is slower than the first two at will. Xiaojiabiyu is a little shy. Although it has been decorated several times, few thieves steal one or two things from the back wall.
Where to live depends on my personal temperament, but after eight years in Shenzhen, I like living in Suzhou, and besides missing two McGee burgers in 10 yuan, it's only a 30-minute walk to Shanghai.
