Tianjin Quanye is a famous shopping mall in China. In the early 1990s, when I was studying in Tianjin University, shopping, of course, was to buy "big pieces" such as radios capable of receiving short wave, mostly to persuade the industry to buy them at a real price. Now, after 17 years of winter, I come to Tianjin again, and once again to the business circle of Binjiang Road, Heping Road. It is more prosperous than before, and has become the Jinjie Pedestrian Street. In the evening, with bright lights and crowded people, it is very difficult to rush. Like Mingdong in Seoul, Korea, it is very busy and has a strong commercial atmosphere. It has become a good place for people to shop for gold. Battery trucks, which are not enough in the United States, have a bad view, but also give people a sense of insecurity when shopping on foot. When walking and stopping, we need to pay attention to them.
