Why is Luban's craft lost?

When it comes to carpenters, Xiao Zhi will think of "Master Lu Ban", the originator of carpenters in China. Lu Ban was a native of the State of Lu in the Spring and Autumn Period, a famous architect and architect in ancient times. He lost his last name and his first name is the same. Later people called him luban. In the era of frequent battles, he used his wisdom to create siege and ship station equipment such as "ladder" and "iron hook". Nowadays, hand tools used by carpenters, such as drilling, planing, shoveling, ruler and Mo Dou for marking, are said to have been invented by Lu Ban. The invention of each tool is inspired by Lu Ban's production practice, and has been repeatedly studied and tested.

Woodworking is a traditional and ancient industry. From ancient times, we can see the long and brilliant development of China's timber industry. In modern society, he has not disappeared with the passage of time, but will have great development prospects. With the development of the mechanized era, many young people in society are unwilling to suffer hardships, and no one wants to do those dirty and tired jobs.

Woodworking is a hard skill, which leads to no young people to learn it, leading to the emergence of "technical fault"

The reason why people don't want to learn Lu Ban Shu is because of the opening sentence. "If you want to learn this book, you must forget it first." Who dares to learn this statement when it comes out? I don't know why Lu Ban wrote this sentence in the book he wrote all his life.

Legend has it that Grandpa Luban was recruited to work in Beijing soon after he got married. Grandpa made a wooden kite because he missed his newly-married wife so much. As long as people ride on it and say a few spells, wooden kites can carry him back to his home thousands of miles away and see his wife. His wife is particularly curious about this. Once, when grandpa came home, he secretly rode on a wooden kite and read those spells. The wooden kite flew into the sky and soared freely. Grandpa, who has been living in the boudoir, was very comfortable. However, the good times did not last long. As the saying goes, there are unexpected events in the sky, and people are doomed. At that time, my grandparents were pregnant, and when they were flying in the air, they suddenly gave birth and blood came out. However, wooden kites were originally made by grandpa in a secret way. When it was defiled, the magic suddenly disappeared, and grandparents suddenly fell from the air and died together with the children in their bellies. Grandpa Lu Ban, who knew this, regretted it, so he cursed all the people who studied Lu Ban's book in the world. Who dares to learn this curse? It's really daunting
