The Great Dictionary of Chinese Idioms gives two examples, one is the "Five Lantern Society Yuan Tianyi Cong Zen Master": "Like a vine leaning on a tree, things are clustered." The other is Lu Xun's "Book of Two Places": "Today I sent a copy of "Red Rose", and the photos of Chen Xiying and Ling Shuhua were all on board. Hu Shizhi's poems are published in "Saturday", and their images are found in "Red Roses", and the power of the old man of time can really gradually reveal the truth of 'things clustered together'. Obviously, the clustering of things is used as a derogatory term. The earliest source of this idiom is probably the Warring States Strategy Qi Ce III: "Chun Yu Yu (kun) one day and seven people Yu Xuanwang." The king said, "When the Son comes, the widow hears of it, and a man who is a thousand miles and a man stands shoulder to shoulder, and a hundred generations and one saint, if he follows with him." When I see the Seven Scholars, will the soldiers not be the same? Chun Yu Jie: No. The husband and the bird live with the same wing, and the beast walks with the same foot. Chun Yu Jie is a person who has seen flocks of birds move and fly.
Bird waves
Chun Yu May understand birds and be good at talking about birds. The most classic is still the famous sentence that triggered the King of Qi Wei, "If this bird does not fly, it has soared into the sky; if it does not sound, it has been a blockbuster." The king of Qi Wei was the father of King Xuan of Qi, who had "drunk for a long night of lascivious pleasures", and no one dared to advise him, and Chun Yu saw the king and said, "There are great birds in the kingdom, and when they reach the king's court, they do not fly and do not sound for three years, and the king knows what this bird is?" This inspired the ambition of King Qi Wei, "Thirty-six Years of Wei Xing". The history books record this, but I don't know what Chun Yujie would have said if King Qi Wei had not answered in this way. Using birds and objects as metaphors for people, saying that people, the ancients were very good at it, which implied that the speaker must be good at observation, otherwise there is no way to say. In ancient times, the land was sparsely populated, there were few people and many birds, and there were many people who hunted birds, hunters hunted, of course, they understood birds and animals. There are many people like Chun Yujie who have left a name in history, are good at observing nature and participating in social affairs.
Autumn birds migrate south, and those who live by the sea naturally have the opportunity to see a large flock of plovers and spectacular flight teams. Especially in some bays and estuaries, the habitat is suitable, the food is abundant, and if there is no major change, it will be used as a migration station by the plover every year, where they stop to replenish their energy in order to continue to fly. Recently, in the autumn, I went to Laoshan to see the Taiqing Palace, where the Taoists were once famous for Pu Songling's "Laoshan Daoists", and on the way back, they passed through Aoshan Bay and encountered thousands of plovers stopping here. After a little observation, it is found that the water birds are indeed "living together in the same wing". Birds at the water's edge of the bay, from the inside out, are divided into three layers gathered together, the outermost water is deep, about 400 white-waisted sandpipers stand, spaced a distance near the shore, the shallow water is densely packed with large sandpipers, and then inward to the mudflat, densely packed is the black-bellied sandpiper. This huge flock of birds, distributed from the inside out, is estimated to total about 4,000.
In the far southeast, there was a white line, a group of more than 180 regurgitated sandpipers, and near it there were a dozen cocked-nosed ducks floating in the water. The ducks came early. Near them, there are 5 black-faced spoonbills standing in the water. Flocks of gulls gathered on the shore to rest, not many, not dense, shining white in the slanting sun. The water ripples, the sun shines, a quiet bird world. Suddenly, the black-bellied sandpiper on the outermost part of the circle flew up, densely packed, somewhat chaotic, and soon adjusted, dense and measured, and the wings flapped at the same frequency, first close to the surface of the water, then pulled up, then pulled up, concentrated, formed into an ink droplet, rotated, descended, scattered, re-pulled, concentrated, opened, like a net thrown by a fisherman to the surface of the water, and quickly retracted, S-shaped drift, and then landed on the distant beach. The speed of action is so fast that one person's thinking and reaction are far less than the speed at which a huge group moves and adjusts. After a while, the original middle layer of the big sandpiper staged again. In the whole process, only the white-waisted sandpiper did not perform.
The outermost white-waisted sandpiper can be seen in the white and black regurgitated sandpiper
The middle layer is the great sandpiper, and the inner layer is the black-bellied sandpiper
Birds are divided into flocks and are clear at a glance
The formation of a wave of birds, such as the take-off of the black-bellied sandpiper, does not affect the great sandpiper, and vice versa, each has its own order. The black-bellied sandpiper population is interspersed with a number of other species, such as a small number of ring-necked plovers, Mongolian sandplings, and a few broad-billed sandpipers. Within the GreatEr Shore Sandpiper Group, there are a small number of gray-spotted plovers. A small number of individuals in the mix follow the actions of the large group. The actions of one group do not necessarily affect other groups. Sometimes they also take off at the same time, forming a larger wave of birds, three or four thousand, which is spectacular. The beauty of bird waves is all in it. Bird wave form, unpredictable, concentrated and scattered, comfortable, no leader's orders, but always consistent action. In the group, the distance between individuals, just right, I don't know how to calculate, seems to have been studied and deduced by mathematicians.
Each bird in the bird wave is in line with its neighbors, changing direction, rising and falling, spreading out and concentrating, and highly unified. When the direction changes, the flight speed and distance between the individuals inside the group and the individuals outside the group are not the same. How are they calculated? There will never be a collision. Such a process, which only a mainframe computer can simulate, still requires human intelligence. One bird is small, and the power of thousands of birds to act in unison cannot be underestimated. Spectacular, breathtaking, merely descriptive, literal, literary. Expressed mathematically, modeling, can be done, but the difficulty is not small. On the calm sea, such a big drama can be watched, praised, and sighed. If you simulate it, who can do it? When I stood on the edge of the bay, it seemed so small.
There are more than 180 anti-billed sandpipers
Different species are bounded to each other
I crouched down and could get close to the individuals scattered around the edges. One by one, the black-bellied sandpipers, with no one in sight, were looking down to feed, and some were less than 5 meters close to me. The abdomen of individuals has black spots, which are the remnants of spring and summer wedding dress, and seem to be reluctant to fade. In the whole group, there are still a few black-bellied people who are distinct, probably really disciples and the like. In the group of black-bellied sandpipers, there are several broad-billed sandpipers mixed in, and the head has obvious longitudinal patterns, the so-called double eyebrow lines, which can be known at a glance. A small number of ring-necked plovers and Mongolian sand plovers are mixed in. In general, the species purity of the flock is extremely high, and there are very few mixed species. At present, it is the end of the southward migration of the plover, and in this large group of about 4,000, the great sandpiper, the black-bellied sandpiper and the white-waisted sandpiper are the main species, and there are very few other species. This number is not clear compared with the number of northward migration in the spring, more or less.
Up close to the black-bellied sandpiper
From the late 1990s to 2005, large-scale sandpiper surveys were conducted along the Yellow Sea coast, Bohai Bay and Liaodong Bay, and data from many sites over the years showed that the GreatEr Shore Sandpiper and the Black-bellied Sandpiper were important species of transiting sandpipers. For example, from April 4 to 10, 1999, the Yellow River Delta northward migration of plover sandpiper survey, a total of more than 64,000, of which the number of ring-necked sandpipers is the first, the number of black-bellied sandpipers is the second, 13450; in 1998 and 1997, the number of black-bellied sandpipers was 14411 and 24106 respectively, accounting for the first place. In 1999, the number of white-waisted sandpipers was the third, with 9766; at this time, the number of large sandpipers was small, 1126, and from April 27 to May 7, 1998, the number of large sandpipers was 12816, and in 1997 it was 11957. From April 29 to May 2, 2004, 6700 large sandpipers were surveyed along the northern coast of Jiangsu, ranking second; black-bellied sandpipers were third, 2453; from May 3 to 4 of the same year, Jiaozhou Bay counted 4900 black-bellied sandpipers, ranking second, and red-bellied sandpipers ranked first, the same as Jiangsu; on May 6-10 in Laizhou Bay, 9430 black-bellied sandpipers were counted, ranking first. The number of large sandpipers in Jiaozhou Bay and Laizhou Bay is very small, with 20 in the former and 351 in the latter.
White-waisted sandpiper
Great Sandpiper
Things are clustered in different densities
Aoshan Bay is much smaller than Jiaozhou Bay, and what I saw was one of the corners, and it was not clear whether there were any sandpipers on the other beaches at this time, and how many there were. But in terms of the current time and the corner of the local bay in front of you, there are 4,000, and the number is not small. My trip to Laoshan is enough.
