Prejudice is very different from looking at the scenery. The scenery hasn't changed, but it will be very different if people who look at the scenery wear colored glasses. Of course, people who are biased do it on purpose, generally following the example of Huineng, a famous monk in the Tang Dynasty, and advocating "nothing outside the heart". When you look at things and think about problems, you can't help adding a pair of colored glasses to your heart, and then you will shrink your head in your stomach, just like Xingtian people, and you will be blinded by audio and video. In this way, prejudice is formed.

When each of us is in the same environment and different moods, prejudice will suddenly pop up from behind our inner sunglasses. On the same night, "happiness is too short and boredom is too long" is the truth. The world is like this, and so is the world. In French, "happiness" consists of two words: "good" and "hour", while in German, "dull" literally means "a long time". An hour is neither long nor short, but it is because of the prejudice of the mind that happiness and desolation appear.

"Prejudice" and "preference" are inseparable twins. "Preference" inevitably produces "prejudice", and "prejudice" favors the favored. The description of woodpeckers in Shelley's To Jenny-A Memory says that "Yin Gong Shan is more secluded", and the famous sentence of the Wang family also says that "cicadas make Lin Jing more secluded", while Wang Anshi's world outlook is quite different from the previous two. He wrote: "A bird without singing the mountain is more secluded." Later generations ridiculed it as a poor handwriting, which shows that Wang Anshi thought it was "crow and magpie noise" that ruined the scenery, while Shelley and Wang Ji praised it as "birds crow and swallow words"

We are afraid of prejudice, even more so. "Everyone is fighting for gold, and there are no bones." So I doubt myself for no reason, but I doubt others more. I often look at my conscience to see if I wear colored glasses, and I often suppress the gap in my heart to prevent "preference" from taking advantage of it and "prejudice" from taking advantage of it. But if you go on like this for a long time, you will be physically and mentally sleepy.
