When the crow flew back to the nest, the family saw the token on the crow's foot and knew that the man was safe outside.
There is another reason why Manchu people have feelings for crows. According to Aisingiorro's royal genealogy "The Preface of Jade Death", "Fan Zu, whose name was passed on, has a restless country and hides in the wilderness. Crows cover their heads and chase after suspected dead trees."
It tells the story of an ancestor named Fancha in Eisingiro who was chased by the enemy during the period of racial chaos. I finally escaped to the bushes in the wilderness, and I didn't have the strength to escape. On the verge of being overtaken by the enemy, at this moment, a group of crows fell from the sky and landed on the bushes, crushing a large area. The enemy thought it was a pile of dead branches, set a fire, and then chased it forward.
After Fancha escaped, he warned his descendants that his life was given by a crow, so don't shoot a crow.
Extended data:
Crow is one of the cleverest birds. As we all know, crows can use tools.
In order to further study whether crows can make tools, researchers from the Institute of Ornithology under the Max Planck Institute in Germany and Oxford University in England designed an experiment.
They showed each of the eight new crows a box they had never seen before, and put food behind a transparent door, but these crows could not directly open the latch with their beaks to get food.
When the researchers provided crows with a long stick, all crows "knew" to put the long stick in the gap of the box to move food. Subsequently, the researchers increased the difficulty, not only put the food farther away from the crow, but also provided the crow with a shorter tool, so that the crow could not directly touch the food with a single tool.
It turns out that a crow can combine three or four small parts to "make" a longer composite tool.
