The poem "I don't know the true face of Lushan Mountain, but I am only in this mountain" comes from Su Shi, a great poet in the Tang Dynasty. The whole poem is: "Looking horizontally, the ridge side peaks, and the distance is different. I don't know the true face of Lushan Mountain, but I am in this mountain. " I don't know the true face of Lushan Mountain, but I am on this mountain. "It means: Why can't I see the true face of Lushan Mountain? Because I am in the deep mountains, I can only see a small part of Lushan Mountain. These two sentences tell us that the content of the same thing is different from different angles. So when we look at the problem, we should analyze it from different angles and not be confused by superficial phenomena. Nowadays, people often use these two poems to describe the truth that "the authorities are fascinated and the bystanders are clear".
I think this is the same reason that our classmates buy snacks to eat. I just think this snack is delicious. I bought it without looking at whether it has expired or whether it is good for my health. Therefore, you should think twice before you do anything in the future.
