Slowly lift the fruit handle of durian, face the tail to the ground, and hit the ground, so that it can be easily opened. However, the opened pulp is all split, and it can't be saved if you eat it as soon as possible.
If there is no crack in the durian to be opened, and it has completed maturity. At this time, you can cut a small part of the tail. After cutting, you will see the lines on it. Insert the fruit knife into the crossing point of the lines, and then cut along the lines.
