Method 2: Cut two knives along the flat stone of mango, and separate the stone and flesh with skin into three pieces. The pulp part is cut inside several times with a knife to make it square. Don't cut the skin with a knife tip, and then push the pulp into the middle of the skin to make it pineapple-shaped, which is very convenient to eat.
Method 3: First cut a knife along the flat core and divide it into two pieces. Cut the skin off the side with the core a little, then draw a circle along the shape of the core with the tip of the knife, put the knife flat on the bottom of the core, that is, the side that has just touched the core, and walk carefully until the core is removed.
