That's deep

In an ESL class, I mentioned this quote from Deng Xiaoping: “It doesn't matter whether the cat is black or white, as long as it catches the mouse" (which I found in this article about the business climate in China).

A student shared a couple of wise Chinese sayings that will encourage people to study:

"The book mountain has its path, and it is diligence."

"Working hard is the boat in the study ocean."

That's deep, n'est-ce-pas?
