There are two stories: there is a tropical ornamental fish. No matter how long you keep it in a fish tank, you can only grow to two or three jumps. But it can grow to more than a foot in two or three months in a big pool. A wolf is an animal full of interest in its surroundings. It is precisely because of its constant exploration and experience that it can avoid risks, find food and survive.

I have to admit that this is caused by the environment.

In junior high school, I saw a picture in a geography textbook. An apple tree said to a coconut tree, "Welcome, welcome, welcome to my hometown." But the coconut tree trembled and said, "It's too cold for you here." Yes, coconut trees grow in the warm and humid south all the year round. How can they stand the cold and dry weather in the north? The difference in environment makes the trees in the two places have diametrically opposite appearances. Trees in the south are as tall as coconut trees and have wide leaves, which are convenient for heat dissipation. Like apple trees in the north, they absorb water and keep warm with narrow leaves.

Another example is the plants in the water, twisting their soft bodies and swaying with the waves, while the cactus in the desert, with its prickly body, stands upright and does not move in the hot sun. Imagine that if plants as hard as cacti grow in water, they will be crushed by the extremely high pressure of water, while aquatic plants grow in the desert, which may have been buried by the vast yellow sand.

Camel is an animal that walks in the harsh desert environment. It has a thick insulated sole and a hump that can store water and energy. Fish swimming in the water have fins, animals in the forest are good at climbing, and animals on the grassland are good at running. These are all caused by the environment.

This is true of trees, animals and plants, and so is human beings.

Not to mention the Eskimos living in the Arctic, whose skin is white; On the other hand, the inhabitants of the African continent have the same skin color as carbon black. Needless to say, Mongolians who wear cotton robes to eat mutton and Southeast Asian residents who wear grass skirts to eat grilled fish, not to mention Arab women who cover their faces and British women who show their big necks. Isn't this enough to prove the influence of environmental differences on people? Yes, the rich and colorful regional cultures all over the world are created by the environment.

The ancients often said: "Those who are near Mexico are black, and those who are near Zhu Zhechi are black." This is what my parents taught me the most. They always use this to warn me to be careful in making friends. In fact, I am afraid that the bad environment around me will affect me. After all, friends also represent your environment. If you just hang out with a group of irresponsible people all day, over time, your words and deeds will only become more vulgar, not elegant. If you spend a lot of time with excellent people, you will find yourself improving gradually. "Always stand on the shoulders of geniuses and listen to their voices. Over time, you will become a genius." I think this is also the reason for the "Three Major Movements in Meng Mu".
