The reason why Kelboro ham sausage is sold less in the south may be that the taste does not meet the taste preference of the southern market. In addition, the southern market may pay more attention to health and light taste, while Kelpolo ham sausage has a relatively heavy taste, so its sales in the southern market may be relatively small. In addition, it may also be because of the differences in food culture between the north and the south, which leads to the sales of Kelpolo ham sausage in the southern market being less popular than that in the northern market.
