Three. Idiom story

In autumn and the season of mountain torrents, many rivers flow into the Yellow River. The river is so wide and turbulent that even cattle and horses can't tell the sandbars on both sides of the river from the water. So the river god gloated that all the beautiful things in the world were gathered here. The river god followed the current eastward to the North Sea. Looking east, he can't see the end of the sea.

So the river god just changed his smug face, looked up thoughtfully at Poseidon and sighed. As the saying goes, after listening to hundreds of truths, he felt that no one in the world could compare with himself, and he was talking about people like me. In addition, I also heard that Kong Qiu knew too little, and Boyi's lofty justice was not worthy of attention. At first, I couldn't believe it. Now I have seen with my own eyes how vast you are. If I hadn't come to your house, it would have been dangerous. I'll make a fool of myself.

If Beihai says frogs in the well can't talk to them about the sea, it's because of the limitation of their living environment. In summer, insects can't talk to them about ice and snow, because they are limited by time, and ignorant people can't talk to them about reason, because they are bound by education. Since you have come from mountains and rivers and seen the sea, you can understand that your knowledge is humble, so you can talk to you about the truth.
