The Story of Lu Ban's Invention of the Saw

The story of Lu Ban's invention of the saw has been passed down in folklore for thousands of years. According to legend, one year Lu Ban was given the task of building a huge palace. The palace needed a lot of wood, so Lu Ban had his disciples go up the mountain to cut down the trees. Since there were no saws at that time, his disciples had to use axes to cut down the trees, but this was very inefficient, and the craftsmen got up early every morning and worked hard to do it. Exhausted, but also can not cut down the number of trees, far from meeting the needs of the project, so that the progress of the project is delayed again and again, and see the project deadline is getting closer and closer, which can be anxious Lu Ban. For this reason, he decided to go up the mountain to check the situation of felling trees. When he went up the mountain, because he was not careful, he inadvertently grabbed a handful of a kind of weeds growing on the mountain, but all of a sudden cut his hand. Lu Ban wondered why the grass was so sharp. So he picked a leaf to observe carefully, and found that there were many small teeth on both sides of the leaf, and when he touched it gently with his hand, these small teeth were very sharp. He realized that his hand was cut by these small teeth. Later, Lu Ban saw a large locust on a grass to eat leaves, two large teeth very sharp, open and close, and soon ate a large area. This also aroused Lu Ban's curiosity, he grabbed a locust, carefully observed the structure of the teeth of the locust, and found that the locust's two large teeth are also arranged with many small teeth, the locust is relying on these small teeth to bite off the grass leaves. These two things left an extremely deep impression on Lu Ban, and also inspired him to deep thinking. He thought, if the tools for cutting wood were made in the shape of sawtooth, wouldn't they be equally sharp? It would be much easier to cut down trees. So he made a large bamboo with many small serrated bamboo, and then to the small trees to do the test, the results are really good, a few times to pull the bark broken, and then pull a few times, the small tree poles cut a deep groove, Lu Ban is very happy. However, because the bamboo piece is relatively soft, poor strength, can not be used for a long time, pull a while, some of the small saw teeth broken, some become blunt, need to replace the bamboo piece. This affects the speed of felling trees, using too much bamboo is also a big waste. It seems that bamboo chips should not be used as a material for making saw teeth, and we should look for a material with higher strength and hardness to replace it, and then Lu Ban thought of iron chips. So they immediately went down the mountain, clear the blacksmiths to help make iron with small saw teeth, and then to the mountain to continue to practice. Lu Ban and his apprentice each pulled one end, pulled up on a tree, only to see the two of them back and forth, and in a short time the tree sawed off, fast and labor-saving, the saw was thus invented.

Before Lu Ban, there must be a lot of people encountered the hand was cut by the weeds of a similar situation, why only Lu Ban from the inspiration, the invention of the saw, which is undoubtedly worth thinking about. Most people just thought it was a small matter of life, not worth making a fuss about, and they often forgot about it after they had healed the wound. Lu Ban, however, had a strong curiosity and the right idea, and paid much attention to observing, thinking and studying some small events in life, from which he found methods and ideas to solve problems, and even obtained some creative inventions. This tells us a truth, pay attention to many small insignificant things in life, hard work and thinking, will grow a lot of wisdom.

The sultry night was suffocating, and I was tossing and turning. Outside the window, a bolt of lightning broke through the dark night, the sound of dull thunder like a cannon roar, make people palpitate fear.

A flash of light, a crisp thunderbolt, followed by pouring rain, as if the gods had heard the signal, ripped open the canopy and poured the water of the heavenly river onto the earth.

The wind roared and slammed the door open and fell under the wall, and the chimney made a whimpering noise as if it were drawing in the darkness of the night.

The rain pounded the roof and pounded against the glass, playing an exciting tune.

A small trickle of rain crept in through the skylight, wriggling slowly and leaving curved tracks on the ceiling.

In a moment, the clanging music turned into a single rhythmic melody, the gentle, sweet lullaby that soothed the weary bodies of sleeping people.

The first rays of light that ducked in through the window reported the dawn on earth, and floating in the turquoise sky were white clouds that danced in the balmy breeze, polishing the azure sky.

Birds sang a joyful song, greeted the spitting sunrise; was bent by the storm, the flowers and grasses stretched out, as if just waking up from sleep; snuggled up in the petals, green leaves on the water droplets, golden, as the pearl glittering with light.

The perennial snow of the Alps greeted the sunrise, dressed in rose-colored dress; the distant forest house glittering, as if the girl sent out the autumn waves, so that people's hearts stirred.

The rivers and mountains look like brocade, the scenery is picturesque, and the colorful roses emit a burst of fragrance.

Enchanting and gorgeous spring colors, how wonderful you are!

Last night, the violent nature seemed to destroy the whole earth, but it brought a more gorgeous morning.

Sometimes people are so limited by their limitations that they see only one aspect of things and ignore the unparalleled and harmonious beauty of nature as a whole.
