Why does Miyazaki Hayao especially like to turn people into pigs in animation?

After watching Miyazaki Hayao's cartoon characters, you will find that Miyazaki Hayao especially likes to turn people into pigs.

Because Miyazaki Hayao once said, "Because pigs draw much better than camels and giraffes." Although this is just a joke, there is another reason why he uses "pig" as a medium to convey his thoughts. The behavior of pigs is very close to that of humans. For example, human's round belly makes us look like pigs, and pigs are close to us. To describe a person as fat means that he is as fat as a pig.

Therefore, Miyazaki Hayao especially likes to turn people into pigs in animation.
