The running water does not compete for the first place, but the eloquence competes for it. From the "Tao Te Ching". "Tao Te Ching" is a book written by Laozi. The excerpts are: "If you don't fight to be the first when water flows, what you fight for is to keep flowing. Water is good for all things, but if you don't fight, you don't dare to be the first in the world." It definitely comes from the Tao Te Ching.
