People who live on the sea are always risking their lives, and what people value most is a peaceful, smooth and successful reunion. As a result, a kind of dish-fish roll, which is full of good wishes, appeared in Chongwu, Hui 'an seaside. In the early years in Chongwu area, besides the first course of wedding banquets, fish rolls were also served on holidays or family dinners, so housewives would make fish rolls, but the skill level and raw material quality were different.

There is a saying in Chongwu: "Going out is like throwing it away, and getting started is like picking it up." Most men here go out to sea for many years to make a living, and their work is extremely dangerous. Therefore, psychological reflection of pinning the hope of reunion can be seen everywhere in life customs. Among them, the most prominent thing is that the dishes served at the wedding banquet must be "round in head and round in tail". Fish roll is the first unique dish that must be served at the feast and home-cooked wedding banquet here, and it contains the meaning of wishing happiness and perfection.

Today's Chongwu ancient city is a summer resort that many tourists admire. Looking through the history books, we will find that it used to be a fortress for military strategists. Because the town is located in an important waterway, after the city was built in the early Ming Dynasty, officers and men were stationed there all the year round.

When stationed in the sea, officers and men need to patrol the sea from time to time, and they should prepare sufficient rations before going out to sea every time. Although there are plenty of fish to eat in this area, due to the lack of effective refrigeration equipment, the fish caught each time can not be kept for many days, and the food supply often fails to keep up with the cruise time. In order to meet the needs of storing military food, the money stationed in the sea area at that time was stored for thousands of households, so the soldiers were allowed to fish the mackerel, which was a special product in the strait, remove the bones and take the meat, beat it into minced fish by hand, add sweet potato powder, add some auxiliary ingredients to adjust the taste, and steam it in rolls, so that the treated fish can be eaten at any time, greatly alleviating the dilemma of military food shortage. In this way, military dry food with regional characteristics was created, and its strip-shaped fish products became what locals commonly called "fish rolls".

Time flies, officers and men stationed in the sea area take root and breed here. Although some descendants have changed from soldiers to civilians, people still follow the tradition of living by the sea. There are typhoons along the coast, and the wind and waves often destroy the mast and overturn the boat, which also makes local people pay special attention to "safe entry and exit, family reunion". Therefore, people improved the past "fish roll" of military provisions, and made it into two round strips, which were eaten in important worship and festivals, with the intention of "round head and round tail, long and long". Later, because of the beautiful implication contained in fish rolls, many people in Chongwu began to pay attention to the custom of "no roll is not a feast" in wedding banquets. Wedding banquets often start with a fish ball soup and end in a steamed fish roll, so as to wish the couple a happy life.
