"Deep in the mountains and valleys"
The verse is a quote from Confucius's Analects, Chapter on Yang Hu.
子曰 飽食終日
無所用心 難矣哉
不有博奕者乎
爲之猶賢乎已
Confucius said, "It would be a problem if you just ate your stomach full and sat around all day.Isn't there anyone who gambles? But gambling is still wiser than doing nothing."
