As follows:

1. There are a thousand Hamlets for a thousand readers: This sentence was said by William Shakespeare when he evaluated his masterpiece "Hamlet", and its meaning is Because each reader has different life experiences and feelings, they have different interpretations and views of the same book "Hamlet", that is, each reader has a different standpoint and therefore has a different point of view.

2. Viewed horizontally, it looks like a ridge or a peak on its side, with different heights from near to far: This poem comes from Su Shi's "Inscription on the Wall of the Western Forest", which actually describes what he saw and felt when he visited Mount Lu. It means that Lushan Mountain has crisscrossed valleys and undulating peaks. Visitors will see different scenery depending on their location. Its extended meaning is that because people are in different positions and have different starting points for looking at problems, they have different perspectives.

The philosophical thoughts expressed in Su Shi's "Inscription on the Wall of the Western Forest":

The first two sentences of the whole poem are "Looking from the side, there are ridges and peaks on the side, with different heights near and far", that is, where the visitor is Depending on the location, the scenery you see is also different. The last two sentences, "I don't know the true face of Mount Lu, just because I am in this mountain" are reasoning in the scene. Why can't we recognize the true face of Mount Lushan? Because we are in Lushan Mountain, our field of vision is limited by the peaks and ridges of Lushan Mountain. What we see is only one peak, one ridge, one hill and one ravine of Lushan Mountain, only part of it. This is bound to be one-sided.

This is what you see when you travel to the mountains, and it is often the same when you observe things in the world. This poem inspires people to understand a philosophy of how to deal with people - because people are in different positions and have different starting points for looking at problems, their understanding of objective things will inevitably be one-sided; to understand the truth and full picture of things, we must transcend the narrow scope and get rid of subjective prejudices.
