The method of private visibility does not exist, so in which class the method is called, it is to call the private method corresponding to that class (if it does not exist, an error is reported)

The call to the inheritance Chain Method of the potholes will confuse many people ..

It is recommended to look at c speech implementation class and inheritance... you will understand a lot.
