What are the cheap and delicious food recommendations in your hometown?

My hometown is the entrance of Dabie Mountain. Because of its special geographical location and low terrain, my hometown has become the confluence of Dabie Mountains rivers, so there is a large reservoir near my hometown with beautiful scenery and many small islands, so our reservoir is also a scenic spot-Wanfo Lake Scenic Area. Due to the inconvenient transportation in mountainous areas, the water quality has not been polluted. There are many fish in the lake. Because the reservoir is very big, there are often big fish in the lake all the year round. Just a fish head and a pot. In the past, people didn't know how to keep healthy. They only bought fish. Because fish heads are weighed without fish, many fishermen sell them to local restaurants at low prices. After the restaurant got the fish head, it worked hard to get others to order it. Besides, foreign tourists also want to try the fish here, so fish heads are not as hard to buy as they think. Not only that, the soup cooked with fish heads tastes delicious and leaves a deep impression on many tourists. Therefore, the first battle of Wanfo Lake fish head is not so difficult to buy.
