As is vividly depicted in the picture, a man attempts to fill a basket with water, but water, which symbolizes lessons drawn from the past failures according to the picture, leaks out of the holes of the basket.

It seems to me that this picture aims to satirize those who fail to learn their lessons from the mistakes they have committed.

Ignoring the lessons derived from our previous frustrations is a serious problem both to the individuals and to the society.

As individuals, if we fail to incorporate the experience into our life, we will slip back into the old pattern and repeat our mistakes.

Similarly, unable to assimilate former lessons, the society is bound to get into bigger trouble.

It is known, for example, that about a decade ago Beijing was subjected to an unprecedented sandstorm resulting from the excessive deforestation in the western part of China.

But recently some people are still cutting trees blindly just to make money without taking account of environment.

If they continue to do so, they will encounter more destructive environmental problems.

Personally, I think it is high time that we attached more importance to past lessons so as to avoid taking a roundabout route in the process of development.
