Edison once said, "Books are the legacy left by genius to mankind, passed down from generation to generation, and even more, they are gifts for those who have not yet been born".

People learn about history through books, but history always shows a more dazzling side selectively. For example, when it comes to Su Shi, people think of him as a great calligrapher, a gourmet and a great poet, but they don't know that he is also an engineer full of fantastic ideas. When Wang Xizhi is mentioned, he is a great calligrapher. The first thing that comes to mind is Preface to Lanting, which has the reputation of "the best running script in the world", but they don't know it. Speaking of Lu Ban, I will not hesitate to equate him with the carpenter's grandfather, but for Lu Ban, who has passed away, he is actually more than a carpenter. It was not until more than 2, years later that his other identity was revealed.

talent works, while genius creates.

Lu Ban was a native of the State of Lu in the Spring and Autumn Period. As the most famous craftsman in the Spring and Autumn Period, he was born in a carpenter's family. It can be said that he had been exposed to carpentry since he was a child.

As Han Yu said in "The Ming of Qinghe County Public Housing Cemetery", "He was impressed by his ears and learned nothing." . He was given not only the good environment of a carpenter's family, but also the teaching from his father when he showed his interest and talent in carpentry.

It is said that when he was 15 years old, he had mastered all the skills of his parents, which can be said to be the end of the family inheritance. However, he was not satisfied with the wisdom of his parents, but began to explore more unknown fields. In the pursuit of Excellence, he created many carpentry pioneers, and made many woodworking creation tools alone, which brought unimaginable improvements and changes to the cause of carpentry, and it still has far-reaching influence.

Even in the modern era of automation and mechanization, tools such as ruler, Mo Dou and saw created by Lu Ban are still used by people and still occupy a very important position. So it is not difficult to imagine that the invention and use of these tools at that time not only liberated carpenters from heavy labor, but also raised the work efficiency and cost, and even opened up a brand-new look for woodworking technology, thus establishing his position as the ancestor of China craftsmen.

what is beneficial to people is called cleverness, and what is not beneficial to people can only be called clumsiness.

At the same time, in addition to the invention and creation of various tools, Lu Ban has also made great achievements in organ skills. According to Mozi's Public Transport, "The public transport disc is the instrument for Chu to build a ladder, and if it is successful, it will attack the Song Dynasty". In the book Mozi Lu Wen, it is expounded that the hook and gun pass through the road: in the decisive battle between Chu and Yue, the Chu people approached along the current, retreated against the current, and chose their own marching mode according to the war situation. Therefore, the Vietnamese people were defeated by the Chu people, and the name of hook-strong water weapon was started.

Invented a weapon that shines brilliantly on the battlefield, a ladder for siege, and a hook for breaking the sea. At that time, it was recognized and appreciated by the rulers. As the name implies, the ladder is easy to understand, and the hook strength is also called "hook rejection". It is said that when the opponent is at a disadvantage, the "hook" can "hook" the opponent to further control the situation, and when the opponent is at an advantage, it can resist the opponent's attack through "rejection", so that there can be corresponding contingency methods in both advantages and disadvantages, thus being invincible.

There is even a story about the karma between Lu Ban and Mozi. As an excellent military expert, Lu Ban and Mozi's advocacy of peace and opposition to war all their lives can be said to be natural opposites. Therefore, when Lu Ban used the ladder to help Chu attack the Song Dynasty, Mozi led troops to block each other, and in the palace, clothes represented the city and bamboo pieces represented the equipment, and simulated battles were carried out. In the end, Lu Ban's means of attacking the city were exhausted, and Mozi still had many ways to defend the city.

the truth hidden in the legend

In carpentry, it can be said that Lu Ban's achievement is the last one. He is very creative, and he has another very secret identity in the known "ancestor of craftsmen". If you want to explore his other identity, you have to say a wonderful book "Lu Ban Shu" written by him. The reason why it is called a wonderful book is that there is a legend that has to be mentioned in the middle.

It is said that when Lu Ban's wife was pregnant, she was recruited to work in Wangcheng. Because she missed her too much, Lu Ban made a wooden kite, which can be said to be the predecessor of today's plane. When she started it with a switch, she could fly in the sky like an airplane, which made her very curious. When Lu Ban was not at home, she couldn't help but start the switch and fly in the sky with a wooden kite, but her wife was not familiar with the operation, so she fell off the tree. At this time, his wife was still pregnant with an unborn child. This accident made Lu Ban feel sad and very guilty. He thought that his skills led to the death of his wife and children, so he wrote a vicious curse on the title page of the book: It is said that anyone who studies the Book of Lu Ban is bound to get one of "loneliness, widowhood, loneliness and disability".

Therefore, people who have studied the book of Lu Ban in all previous dynasties will have a lingering fear when they see the words on the title page, and even many people give up their research because of this, which also puts a more mysterious veil on the book of Lu Ban, which is full of myth. In real time, The Book of Lu Ban is divided into three volumes, mainly involving the skills of craftsmen such as civil architecture. The core content of this book can be elaborated from two aspects, which is divided into two parts. The first part mainly involves buildings such as houses and buildings, as well as the strange skills of structure and construction in houses. However, the latter part has little to do with civil architecture, but more about Yin and Yang gossip and geomantic metaphysics. It can be said that Lu Ban has become a master of geomantic omen from a preacher here.

Of course, the original purpose of "The Book of Lu Ban" is not the so-called shocking contents such as incantations and spells, but I hope that every generation of craftsmen can take into account a more comprehensive direction while studying their own skills, and observe the laws of nature while studying architectural skills. In popular terms, it is to look at "Feng Shui", but with Lu Ban's extraordinary creativity and wisdom, it is more ingenious to integrate natural science such as Yin and Yang gossip into the book.

Maybe now it seems that craftsmen and geomantic omen are two totally different things, but back in the past, it was very reasonable. At that time, people were superstitious and recognized geomantic metaphysics. From dignitaries to ordinary people, they invited geomantic omen masters to make a special survey to see if they could build their homes into a treasure trove of geomantic omen, and they were convinced that geomantic omen would affect their families' career or health. As a craftsman, if you want to build a satisfactory tool or house, you can't meet their needs just by outstanding craftsmanship without knowing anything about Feng Shui, and it is even more difficult to realize that your works will last forever and become a great craftsman.

Conclusion: We may be biased, but fate is not biased.

As we all know, reading should not be biased, but people often have a fixed impression on a thing or a person, and it is hard to change it. For Lu Ban, even if you know today that he is not only the granddaddy of carpenters, but also a warlock of yin and yang, you will think of the originator of carpenters tomorrow.

Although numerous experts and scholars have renamed his book "Lu Ban Shu", there are still many people who misrepresent it. Not only ordinary people, but also in some legendary film and television dramas, they will focus on mentioning the words on the title page, which makes the mystery of this book more dense. Some people even regard him as a book of cultivating immortals and monasteries, which is ridiculous. However, due to the particularity of Lu Ban Shu itself, it was banned after many dynasty changes, which also led to the fact that its original text could not be verified, thus becoming a generation of wonderful books. Even if only a few words were circulated, it did not prevent us from re-recognizing his identity as a wizard of Yin and Yang more than 2, years ago.
