可持续发展不是口号，而是必须践行的理念，我们要让土地永远充满生机。

The most powerful art is often the most humble.

The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

"We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don't let yourself be lulled into inaction."
