Word: to test resistance, paper bags are far and strange all the way. Confirmed speculation, extraordinary flight, including instinct, almost check, probably amnesia, is it allowed?

Test link:
Step 1: I caught some bees in the hive of my garden and put them in paper bags.
Step 2: I made white marks on their backs.
Step 3: I told my little daughter to wait by the hive.
Step 4: I walked two miles with twenty marked bees, opened the paper bag and let them all out.
Test conclusion:
It is said that bees have the ability to tell directions. Wherever they fly, they can always go back to their original place. "I" confirmed this statement through experiments. The ability of bees to tell directions depends not on extraordinary memory, but on instinct that I can't explain.
3. Knowledge about bees
Bees rely on two skills to find their way: one is polarization navigation and the other is aroma corridor. Polarization is ultraviolet light invisible to human eyes. Using this polarization, bees can perceive the sun and fly back to their nests accurately. Bees have an olfactory gland in their abdomen. When bees fly, their bellies contract, and the aroma secreted by olfactory glands stays where they fly. The bees behind follow the aroma to collect honey. Many bees come and go, forming an "aroma corridor" between the honey source and the honey room. Along this "fragrance corridor", bees will not get lost when they collect pollen and go home.
4. Introduction to the author?
Fables (1823— 19 15): a famous French scientist and popular science writer. Living in poverty since childhood,/kloc-was admitted to a normal school at the age of 0/5, and taught mathematics in junior high school after graduation. Once I took a student to an outdoor geometry class. Suddenly, I found bees and beehives on the rocks. Since then, the "worm heart" has been rejuvenated. He spent a month's salary, bought a book on entomology and decided to be a person who wrote history for insects. He devoted his life to the insect world, observed and experimented with insects in the natural environment, and truly recorded the original energy and habits of insects, and wrote a masterpiece Entomology with a volume of 10.
The original "Bees":
It is said that bees have the ability to tell directions. Wherever they fly, they can always go back to their original place. I want to do an experiment.
One day, I caught some bees in the honeycomb in my garden and put them in paper bags. In order to prove that I set the bees flying back to the garden, I made a white mark on their backs. Then, I asked my little daughter to wait by the beehive, walked more than two miles with twenty marked bees, opened the paper bag and let them out. Those bees that have been bored for a long time are flying in all directions, as if looking for the direction to go home. At this time, the wind blew, and the bees flew very low, almost touching the ground, probably reducing the resistance. I thought, how can they see the distant home when they fly so low?
On the way home, I speculated that the bees might not find their home. Before she stepped into the house, her little daughter rushed over, blushing and looking very excited. She shouted, "There are two bees flying back! They returned to the hive at 2: 40, covered in pollen. "
It was two o'clock when I released the bees, that is to say, in forty minutes, two little bees flew more than two miles, including the time to collect pollen.
It's getting dark, and we haven't seen any other bees fly back. When I checked the hive the next day, I found fifteen more bees with white spots on their backs. In this way, seventeen of the twenty bees did not get lost and returned home accurately. Although they flew against the wind and had some strange scenery along the way, they did fly back.
Bees don't rely on extraordinary memory, but an instinct that I can't explain.
