You would find it very interesting and contradictory that Han Chinese themselves call each other “Pig/dog” and at the same time they force everybody to think Han Chinese ethnic group “the superior ethnic group”.

Why?

That phenomenon can be easily explained.

It is because Han Chinese personality is one-sided and their pursuit of being arrogant.

Then, the partial personality and their pursuit make them look down on each other and offensively call each other “pig/dog” to make themselves be the superior and can be arrogant, and the same reasons make them have to force everybody to think Han Chinese ethnic group “superior”, and then they can be arrogant in the world.

So, Han Chinese make themselves “the superior pig ethnic group”.
