Matters needing attention in opening cans

1, find the can lid: first you need to find the can lid. Most cans have a small handle that can be used to open the lid. If you can't find the handle, try to find a gap in the edge of the jar and pry it open with a knife or pliers.

2. Keep clean: Make sure your hands and tools are clean before opening cans. This will prevent bacteria or other pollutants from entering the food.

3. Use a knife or can opener: It is easier to open cans with a knife or a special can opener. Make a knife on the edge of the can, and then gently pry open the lid. If there is no knife or can opener, you can open the can with pliers or screwdriver.

4. Beware of liquid splashing: When the can is opened, some liquid may splash out. To prevent this from happening, you can put a bowl or plate under the jar.
