Encounter one obstacle after another, but don't care, it just gathers into a stream of water, as if straining muscles in the inevitable struggle.

………

The stream struggled forward in the tight cracks between the two banks, calling each other and saying the word "sooner or later". The voice of "sooner or later" keeps ringing all day long. When the last drop of water has not run out and the spring has not dried up, the water always keeps saying, "sooner or later, we will flow into the ocean."

………

The water flows smoothly in the restrained noise, and they are so excited that they can't help calling each other: many powerful water flows come together to form a big water flow, talking to each other and calling each other-this is the greeting of all the water flows that come together and want to separate.
