Human society is always progressing. From the evolution of people's bathing methods, we can see that human progress can not be underestimated. We humans didn't take a bath from the beginning, and gradually developed and evolved. Humans never wear clothes but cover their bodies with leaves. They also gradually realized that they should be clean and really comfortable after washing their bodies, so they began to take a bath.
At first, I was caught in the rain, and then I went to the river to take a bath. I thought it would be more comfortable to take a bath in the river, so I took a bath with hot water slowly. A hot bath needs a container, so I pour hot water and cold water into the bucket and take a bath in the bucket. Then, with the development of science and technology and the progress of society, there was electricity, and then someone invented solar energy, so that we could take a hot bath without boiling hot water. With a bathtub, we could take a bath there. Later, some smart people found it quite comfortable when they were caught in the rain, so they invented the shower to make it a pleasure.
The human brain is particularly magical, and the power of people is immeasurable. Human beings have many fantastic ideas, which can be turned into reality in their own way. Many human thoughts come from life, just like taking a bath today, that is, from life. Many things come from life and are beneficial to life. Through the continuous progress of human beings in the way of bathing, we can see that our human wisdom is infinite and our potential is infinite. I firmly believe that our human development will be better and better and more convenient.
