Hello, I am happy to answer your question.
The mainstay is like the mainstay mountain standing in the rapids of the Yellow River. It is a metaphor that a strong and independent person can play a pillar role in a turbulent and difficult environment.
Source: "Yan Zi Chun Qiu Nei Pian Remonstrance": "I tried to follow the emperor to help the river, and the turtle held the left turtle in its mouth to flow into the mainstay."
Story: In ancient times, there was a mountain standing in the rapids of the Yellow River at the narrow channel of Sanmenxia, ??which affected the flow of the river. When Dayu controlled the water, he widened the river channels on both sides, so that this pillar mountain stood like a pillar in the rapids. middle. Sanmenxia is divided into human gate, divine gate and ghost gate. Among them, the ghost gate is the most dangerous, but the mainstay stands majestically in the rapids.
"Yan Zi Chun Qiu Nei Chapter Admonishment": "I tried to follow the emperor to help the river, and the turtle held the left turtle in its mouth to flow into the mainstay." The mainstay is located in the rapids below the Sanmenxia Dam. The boatmen on the Yellow River also call it "come to me", which is about 30 kilometers away from the city. In winter, when the water is shallow, it is more than two feet above the water; in flood season, only a spire is exposed, and it looks as if it will be swallowed up by the flood soon, which is extremely dangerous. For thousands of years, no matter it is attacked by violent storms or washed away by turbulent waves, it has always turned the tide and stood majestically in the Yellow River, like an angry lion, strong and fearless. It has been hailed as a symbol of the spirit of the Chinese nation since ancient times. In 638 AD, Li Shimin, Emperor Taizong of the Tang Dynasty, came here and wrote the poem "Look up at the mainstay, look north at the Dragon Gate, see the vast traces of Yu, and the vast Changchun", and ordered Minister Wei Zheng to stay in the shadow of the mainstay. The famous calligrapher Liu Gongquan also wrote a long poem for it, which includes "A solitary peak floats on the surface of the water, and a pillar nails the center of the wave. It withstands three dangerous gates, and its roots are connected to nine deep bends. The pillar's shape is abrupt, and it floats and sinks according to the waves." Good sentences.
I hope you will adopt it. If you still don’t understand anything, you can continue to ask me.
