We can judge whether the yellow-margined box turtle knows its owner through the following points:

1. After getting to know the owner, the yellow-margined box turtle will not be as enthusiastic about the owner as the dog, but it will quickly swim to the owner and stretch its neck. Looking for the owner to eat, it will not retract its limbs out of fear.

2. After getting to know the owner, the yellow-margined box turtle still likes to stare at the owner. When the tortoise is placed on the ground, it can still follow the owner's footsteps. It has been raised for a long time. When the owner calls it, it can also respond accordingly.
