"No stupid apprentice, only stupid master"?

Personally, I think there are two situations here:

1. The apprentice studies hard, but the master is always careless in education. This is the master's fault. No stupid apprentice is worthy of a stupid master, otherwise it is the second case.

2. The master tried his best to teach, but the apprentice just didn't listen, and he was confused all day. In other words, there are no poor teachers, only poor apprentices.

Amount,

I hope the landlord will adopt it

But I don't know where this language comes from.

pity

I wish the landlord a smooth game.
