Fried squid suddenly disappeared because of poor management and declining sales. The early success of fried squid mainly benefited from changing the traditional consumption pattern of squid and turning the products previously sold in catering channels into snack foods, which is a business model worth learning. Fried squid is popular because its products are unique and novel in shape and eye-catching. Its small-scale franchise chain model, with less investment and relatively fast income, is very easy to attract entrepreneurs and consumers. However, most of the fried squid shops are "following the trend". Such an operation mode will naturally disappear in the street in a short time, which is the product of blindly following the trend. This kind of affiliate marketing belongs to the standard "eyeball economy". Franchise chain headquarters often only consider profiteering, rarely consider how many stores a city wants to open, let alone whether franchise stores have business licenses and whether they are legally operated. Just to earn the joining fee, blind expansion leads to fierce market competition. After a period of prosperity, operators are faced with the dilemma of decreasing customers or even closing down, and finally the franchisees are unlucky. "Many customers come to buy big squid for early adopters. Once they find that the quality is not too hard and the taste is not good, it is difficult to consume it twice. In the long run, it is difficult for such franchisees to continue to operate. "
