Why do Dapeng birds fly thousands of miles away?

First, the description of Dapeng bird's wings in the article "Dapeng bird's wings cover the sky" seems inaccurate. In class, many students questioned, "wings can cover the sky and the sun is covered." How can people tell? " Although I explained to the students that this was an exaggeration, the students still argued endlessly. After class, I looked up Happy Travel on the Internet and found that the sentence describing Peng in the original text was like this: Peng's back is thousands of miles away; Angry fly (4), its wings hang like clouds (5). From the perspective of "if", this sentence should be understood as "when it rises and flies, its spread wings are like clouds on the horizon." From the perspective of more accurate expression, it is suggested that it is more appropriate to add "almost" as "its wings can cover the sun" after the sentence "its wings cover the sun" in the story or directly interpret it as "its spread wings are like clouds on the horizon". The second is the last sentence of the translation, "Why do Dapeng birds fly to the distance thousands of miles away?" Many students said that Dapeng Bird wants to fly high and far, "live and rest in the South China Sea", several students said "don't waste their talents", and only one student said "show its positive side to the world, not just know how to have fun passively." It seems that this last insight is more profound than the previous ones. However, how can I guide them to understand? How to understand a will that is more in line with the text? I also made great efforts to understand the original text and translation downloaded from the Internet, but I was still in a fog. I have consulted several colleagues, and they probably think that Dapeng flies high and far in order to broaden his horizons and enrich his knowledge, as long as students write rationally. Resting down and rereading the original text and translation, I found a sentence in the original text: "The wind is not thick, and its negative wing is weak, so the wind is weaker than Wan Li (19). Then there are those who plow the wind today (20), carrying blue sky (2 1), and then heading south today. " The wind is not strong enough to accumulate strength, nor strong enough to bear huge wings. Therefore, Pengniao flies high in Wan Li, and the strong wind is under it. Then it flies with the wind, carrying the blue sky, and nothing can stop it, and then flies to the south like now. "So, Dapeng birds fly so high to help them reach the distant South China Sea with strong winds. Now, some clear concepts are confused. I don't know what to tell the students tomorrow. I can't even justify myself! What are we going to do? Am I at a dead end again? Have you complicated the simple things?
