overall, the fish situation in Xi' an is good and distinctive. There are many kinds of fish, such as carp, silver carp, catfish and bighead carp, which are delicious and nutritious, and are favored by consumers.

However, there are some problems in the fish situation in Xi 'an, such as too much fried oil, which reduces the nutritional value of fried fish, and the residue of fried oil will also have adverse effects on human health.

In order to solve this problem, we should first improve the technical level of chefs and let them master the correct cooking methods, such as cooking time, temperature and oil amount, so as to ensure the nutritional value of fish. Secondly, it is necessary to improve the quality of consumers and let them know the harm of fried food, so as to reduce the consumption of fried food; Finally, it is necessary to strengthen food safety supervision and strictly control the use of food additives to ensure food safety.
