Ask where the canal is so clear, because where does the running water come from?

With the phenomenon of fresh water pouring into the pond, this poem means that we must constantly accept new things in order to keep our thoughts active and progressive.

In poetry, this inner feeling is described by symbolic means, so that readers can understand the mystery themselves. The so-called "flowing water from the source" means constantly absorbing new knowledge from books.

Qin Shi is a seven-character quatrain written by Su Shi in the Northern Song Dynasty.

If there is piano sound on the voice piano, why not ring it in the box? If the piano sounds from your hands, why can't you hear the sound?

If the sound of the piano comes from the piano, why can't it be made in the piano box? If the piano comes from your fingers, why not listen to it on your fingers? ?

Appreciation of Qin dynasty;

This poem only uses two rhetorical questions, which shows that the piano itself can't make a sound without someone playing it; Leave the playback tool; People's fingers can't make a sound. Only when people's fingers act on the tool piano can they produce pleasant music.

This actually puts forward an important philosophical proposition, that is, everything in the world is interdependent. People can't leave things, and things can't leave people. The organic combination of people and things can create life and create the world. The whole poem is concise and clear, reflecting the main characteristics of philosophical poetry in Song Dynasty.
