Some time ago, I wrote an essay called "Two Geese", in which the two white swans were defined as "the Great White Goose Couple". The reason why I write this is also from hearsay and has not been verified.
One day Hongbo told me that he had heard that the two geese were brothers. Later, Professor Shen accidentally mentioned the two geese in class, and also said that they were brothers, because the other two white swan sisters absconded together and did not know the end. He also said that the surface of the campus is a world of black swans, and white swans are very excluded and cannot raise their descendants to fight against black swans.
Although there is no scientific method to confirm that both geese are males, this incident has given me a great wake-up call: observing things or phenomena is indeed more meticulous and rigorous, and it is necessary to seek verification in many ways and fulfill the obligation to review the authenticity before drawing conclusions. "Without investigation, there is no right to speak," Shinzo said.
Let's talk about the black swan today.

Black swans dominate most of the campus, and their daily routine is to parade around gracefully. The most handsome moment is when two black swans spread their wings and sprint by, drawing a long line on the surface of the water, a scene that often causes the exclamation of pedestrians by the lake. More often, they love to be clean, bending their long necks on the shore and carefully combing their feathers with their beaks, without staining a grain of dust or staining a trace of worldliness.
Of course, the most representative scenery about black swans is their intimate interaction with koi. At the beginning of the school year, Beigulou students sent me a WeChat video, telling the warm picture of black swan kissing and feeding koi. It feels so loving! It is shocking to see the harmonious coexistence of different species among animals. Animism. My young teacher Sun, who has worked on campus for more than 20 years, once said proudly that the black swans in our school will feed the fish!

After enrolling for a long time, walking next to the winding campus water system, I often encountered classmates shooting "black swans feeding koi". So I was also thinking, what is the biological mechanism behind this phenomenon?
After a long period of continuous and in-depth observation and analysis, it is generally concluded that the black swan feeding koi may be a beautiful misunderstanding. The truth is probably that it is not the black swans who take the initiative to feed the koi. When black swans peck at the dry feed from the shore trough, they must quickly drink some water to soften it, otherwise they may "choke on food". In the process, the feed will fall into the water, and the koi will compete for it. The warmth of "black swans feeding koi" is only a spiritual feeling imagined by our own wishful thinking, which is essentially a struggle for the interests of animals "the people take food as the sky".
Observing the phenomenon of "the interaction between black swans and koi" also allowed me to complete a leap from perceptual cognition to rational cognition. "Black swan feeding koi" is a perceptual understanding, is a "vivid intuition", its one-sidedness, superficiality is obvious, can not reflect the essence of things. Seeing is not necessarily believing. Fa Xiao, who has worked here for more than 20 years, has the obsession of "black swan feeding koi", which shows how deep the foundation of wrong perceptual cognition is, and even stereotypical prejudices are formed.

From the perceptual understanding, rational understanding depends on concepts, judgments, and reasoning. You can't trust the stereotypical description of black swan feeding. Only by seriously multidimensional exploration in the spirit of science, thinking and analyzing the obtained perceptual materials, and removing the coarse and refined, removing the false and the true, from this and the other, from the surface and the inside of the reasoning, can we see the whole, essence and internal relationship of things.
We came to the idea that black swans pecking at the feed triggered koi to grab food and form a landscape. In addition to giving full play to the subjective initiative, fully grasping the actual perceptual materials, conducting long-term and detailed observation of the landscape of "black swans and koi interactions" on the campus, and searching for the keyword "black swan feeding koi" through the Internet, a large amount of such information can also be obtained, and even foreign black swans have such performance art.
Judgment: Set up dry feed tanks in the place where black swans inhabit (if it is wet feed, it will cause mold and cause disease), stocking koi in the lake water, and when black swans peck at dry feed and soften the water, there is a high probability that koi will be attracted to grab food. Over time, the biological mechanism of koi living in groups on the water surface around the feed trough may be strengthened as a memory of koi.
It can be seen that making decisions must not be completely based on perceptual understanding to "pat the head", too much trust in intuition and "common sense". It is necessary to bear in mind Comrade Chen Yun's teachings, "Not only the superior, not only the book, but only the truth, exchange, compare, and repeat," and do a good job in investigation and study. To achieve two leaps, the first leap is a leap from perceptual understanding to the epistemology of rational cognition, enhancing the scientificity, comprehensiveness and precision of thinking, and running dialectical materialism through the whole process of thinking. The second leap is the unity of knowledge and action, from the epistemology of understanding the world to changing the world to the leap of practice, and finally taking practice as the only criterion for testing truth, using practice to prove the shore of thinking and realize the truth of thinking.
This is the inspiration for "black swans feeding koi".
