The method of frying the blood sausage without breaking it up is as follows:

1. First, before frying the blood sausage, cut the blood sausage into appropriate size segments and use a toothpick to cut the blood sausage into pieces. Poke small holes on the surface.

2. Secondly, you can steam the blood sausage in a steamer before frying it.

3. Then, when frying the blood sausage, you can brush a thin layer of oil on the bottom of the pot and fry slowly over low heat.

4. Finally, wait until the surface of the blood sausage is fried until golden brown before turning it over. This will allow the blood sausage to be heated more evenly and prevent it from falling apart.
