Keya's math teacher came up with learning and thinking. Well, if you have to compare, I can only tell you that Keya and learning and thinking are not at the same level at all. ...

Keya is a small organization, and learning and thinking is a large enterprise across provinces.

Look at the washing machine below. It's all thanks to Koya. Please don't put the cart before the horse, do a good job in teaching, don't brag, and don't denigrate others' learning and thinking. You still have to be grateful to your old boss.
