In the vast Amazon tropical jungle, there is a bird flying upside down, called hummingbird. Diary fourth grade diary
Why do hummingbirds fly backwards?
It is said that hummingbirds didn't fly backwards before, but fly forward like other birds. Although hummingbirds are very small, their family is very prosperous. If they all go out, it will be a huge lineup. Their content on this page is pushed by "read. 4hw. Com. CN". Flapping their wings can block out the sun and cover large forests in their shadow. There is also a rule of the hummingbird family, that is, only forward and not backward. If a timid hummingbird retreats, it will be pecked to death by its peers. Until a fire burns, the hummingbird king and many hummingbirds are burned to death, and only the retreating hummingbirds survive.
If everyone knows the truth of taking a step back, what can't pass in life?
