Here we are going to prove that Chinese, Korean, Japaneses and Vietnamese are Mk Language.

Lemma: For Chinese, Korean, Japaneses and Vietnamese, we need to rote every glyph

Premise: Rote-learning is MK Behavior.

Proof:
Rote-learning is primordial mode of learning.
MK learn by mimic.
So Rote-learning is very common for animal.
Since we know that MK is the least intelligent animal, MK must practise rote learning very often.
Then the proof is complete.
