Fine, Meaningful Calligraphy

Painted by a popular calligraphist, Zheng Ban-Qiao.

It says:

"Nan De Hu Tu

It's hard to be smart
It's hard to be "hu tu" (not smart)
Transforming from smart to "hu tu" is harder still

Yield a little
Back down a step
Think and be careful
All for rewards in the future"

(Quoted from China the Beautiful)

Ah~ so meaningful...
