The ancients gained the freedom of water transportation by imitating fish living in water, cutting down trees and chiseling boats, making fish-shaped hulls out of wood, and using fish pectoral fins and caudal fins to paddle and paddle.
The ancients had an extremely profound saying: Learn from nature. Great! Nature has indeed taught us many, many lessons, and each lesson is more exciting than the next. Listen to a story first.
Story 2: In order to dry clothes, someone tied wire to two trees not far apart. Over time, the iron wire formed an iron hoop and was firmly pulled into the trunk, leaving a deep impression on the tree. Two years later, the hoop was deeply pulled into the tree. The poor tree seemed doomed to death, but a miracle happened because of it. The tree didn't strangle, but stood up firmly and swallowed the terrible iron hoop alive! And all this happened to be seen by a desperate old man, and he summoned up the courage to live. The old man has cancer! He overcame his illness and survived. After living for several years, his last words when he died were: Thank you for that tree!
Look! How profound nature is, although silent, it can give people extraordinary power.
Yes, there are many similar stories. Mature ears of wheat droop their heads, which is teaching us humility. A group of ants can carry big bones, which is teaching us unity. Gentle water drops can pass through rocks, which teaches us tenacity. Bees are busy shuttling among flowers, which teaches us to work hard. The poor grass silently closed the leaves, which told us not to overstretch the fields.
Yes, nature is the best teacher. As long as we are willing to study, we will gain something every day.
