Who is the ancestor of civil engineering craftsmen?

The ancestor of the civil craftsmen was Lu Ban

Lu Ban was born in about the thirteenth year of King Jing of Zhou (507 BC) and died in the twenty-fifth year of King Zhending of Zhou (BC 444), he lived from the late Spring and Autumn Period to the early Warring States Period. He was born in a family of craftsmen for generations. He participated in many civil construction projects with his family since he was a child. He gradually mastered the skills of productive labor and accumulated rich practical experience.

Luban has many inventions and creations. Many ancient books such as "Shi Cyan Pearl", "Wu Yuan" and "Ancient History" record that many tools and instruments used by carpenters were created by him, such as the curved ruler (also called the moment or Luban ruler), as well as the ink fountain and plane. , drills, chisels, shovels and other tools are also said to have been invented by Lu Ban. The invention of these woodworking tools freed the craftsmen at that time from primitive and heavy labor, doubled their labor efficiency, and gave civil engineering a new look. Later, in order to commemorate this famous master, people respected him as the ancestor of my country's civil craftsmen.

According to records in the "Shiben", the stone mill was also invented by Lu Ban. Legend has it that Lu Ban used two relatively hard round stones, cut them into dense shallow grooves, put them together, and used human or animal power to turn them, and then grind the rice flour into powder. This is what we call a mill. Before this, people processed grain by putting the grains in a stone mortar and pounding them with a pestle. The invention of the mill changed the up and down motion of the pestle and mortar into a rotational motion, so that the intermittent work of the pestle and mortar became continuous. work, greatly reducing labor intensity and improving production efficiency. This is a major improvement in ancient grain processing tools. The actual situation of Lu Ban's invention of the grinding mill has been unknown, but judging from archaeological excavations, pestles and mortars were already in existence during the Longshan Culture period (about 4,000 years ago). Therefore, it is possible that the grinding mill was invented in Lu Ban's time.

In terms of weapons, according to "Mozi Gongshu Chapter", Luban once manufactured "cloud ladders" for sieges and "Gouqiang" (also known as "Gouji") for water warfare for the Chu State. ), played a relatively large role in the war. In terms of architecture and sculpture, Luban also made many contributions. "Shu Yi Ji" says that Lu Ban carved a three-dimensional stone map of Kyushu.

Lu Ban is indeed one of the best civil construction craftsmen in ancient my country. For more than 2,400 years, he has been regarded as the "ancestor" by civil engineering craftsmen and is respected and commemorated by people.

Luban's surname is Gongshu and his given name is Ban, also known as Gongshuzi, Gongshupan, Banshu and Luban. A native of Lu. He was born in the third year of Lu Dinggong (507 BC) (some say 489 BC); the year of his death is unknown. Mechanics, Civil Engineering.
