Bianhe refers to which river in China?

Centered on the tall towers, there are rows of houses on both sides, including teahouses, restaurants, foot shops, meat shops, temples, public halls and so on. Silk, jewelry, spices, incense, paper horses and so on all have specialized businesses. In addition, there are medical clinics, car repair, fortune telling, shaving and plastic surgery, and all walks of life have everything. Large-scale shops are also tied up with "colorful buildings and happy doors", and banners are hung to attract business, and pedestrians in the market are jostling with each other. There are businessmen who do business and people who look at street scenes. There are monks walking around with baskets on their backs, tourists asking for directions from other places, street children who have heard of books, children of rich people who drink heavily in restaurants, disabled elderly people begging on the edge of cities, men, women and children, scholars, farmers, workers and businessmen, and so on. Means of transportation: sedan chair, camel, ox cart, rickshaw, flat car and various vehicles, which vividly show people the bustling scene of a commercial city.

First of all, the middle area between the Bianhe Wharf and the city gate is particularly conducive to commercial activities. With the absence of war for many years, hotel teahouses have gradually developed, and various shops are lined up, and all kinds of cars and horses are busy. The picture clearly shows that in a wooden workshop, two technicians are nervously rushing to make a mule-horse cart. A shipper rented a donkey on the street corner, a porter was loading on the ground, and a lady was preparing to rent a sedan chair to walk instead of walking. Looking at it again, it is a small labor square and the only way to enter the city. Therefore, business activities are frequent. A fortune teller lost no time in building a house here, and many people who look for his fortune-telling calculations are doing very well. There are many workers in front of the footbridge crossing the Xigou Bridge. Some sit and rest, some doze off, and some simply lie down and rest. Mules and horses are tied to the footbridge. It seems that they are saving energy in order to work energetically after work. Although they have nothing to do, they will not steal other people's business. They abide by the rules of footbridges very much. It can be seen that the business of the workers in the square is very good. One sedan chair has been lifted and the other sedan chair has been taken. A peddler on the bridge has sold out and gone home. Farmhouse Bridge also has some residents and some donkeys. There is a woman with a baby in her arms next to the house, and some fat pigs are lying not far away.
