(1) General description

There are 6 types of occupations in the country, and the 100 workers in charge of construction are one of them. Some people sit quietly and think about how to govern the country; Some people rose up to enforce the ways of statecraft; Some people examine the straightness and square circle of the five materials to process and rectify the five materials, so as to prepare enough utensils for the people; Some people make the circulation of rare items from all over the world for people to buy; Some people work hard to make the land grow rich; Some people weave silk and linen to make clothes. It is the prince who sits down and then contemplates the way to govern the country; It is the scholars who rise up to enforce the way of the country; It is a hundred craftsmen who examine the straightness and square circle of the five materials to process and rectify the five materials, so as to have the utensils needed by the people; What makes the rare items of the Quartet circulate for people to buy is business travel; It is the farmer who cultivates the land so that it grows wealth; It is a woman's work to weave silk and linen to make clothes.

There were no craftsmen who knew how to smelt in Yuedi, no craftsmen who made armor in Yandi, no craftsmen who made long-handled weapons such as spears and halberds in Qindi, and no craftsmen who made bows and chariots in the Xiongnu. There are no craftsmen who can make smelting in Echichi, not that there are no people who can make iron ice chisel tools, but that everyone there can make ice chisel tools. There are no craftsmen who make armor in Yandi, not that there are no people who can make armor, but that everyone there can make armor. There were no craftsmen in Qindi who made long-handled weapons such as spears and halberds, not that there were no people who could make long-handled weapons, but that everyone there could make long-handled weapons. The Xiongnu did not have craftsmen who made bows and chariots, not that there were no people who could make bows and chariots, but that everyone there could make bows and chariots.

The wise man creates the utensils, and the skillful man follows his methods and styles, and this is passed down from generation to generation as a profession, which is called work. The utensils made by hundreds of craftsmen are all created by saints. Utensils that melt metal to make sharp blades, make earth strong enough to make pottery, make chariots to travel on land, and boats to travel on water: these are the creations of the saints.

When the sky is cold and warm, the ground has a rigid and soft atmosphere, the material is excellent, and the craftsmanship is exquisite; Combine these four aspects, and then you can make a fine utensil. The material is excellent and the craftsmanship is exquisite, but the utensils made are not excellent, because they are not in line with the time and the earth. The orange will become a citrus orange if it is planted in Huaibei, the starling bird will not fly north over Jishui, and the raccoon dog will die if it crosses Wenshui in the north: these are all caused by the earth's qi.

The knives of Zhengdi, the axes of Song, the sharpening of Ludi, and the swords of Wu and Yue cannot be refined when they are made without leaving the locality, which is also caused by the local qi. The horns of Yandi, the bow stems of Jingdi, the arrow shafts of Shihu, the gold and tin of Wu and Yue: these are all excellent materials. Heaven sometimes causes all things to grow, and sometimes causes all things to wither; Plants and trees sometimes grow, sometimes they die; Stones can sometimes crack; Sometimes the water solidifies, sometimes the ice melts: these are all caused by the time of day.

There are 7 types of craftsmen who work with wood, 6 types of craftsmen who work with metal, 5 types of craftsmen who handle leather, 5 types of craftsmen who work with dyeing, 5 types of craftsmen who work with scraping, and 2 types of craftsmen who use clay to make utensils. The craftsmen who manage wood are: wheel people, public opinion people, bow people, Lu people, craftsmen, car people, and Zi people. The craftsmen who managed the metal were: Zhu, Ye, Fú, Li, Duan, and Tao. The craftsmen who manage leather are: Han people, Bao people, 韗 (yùn) people, Wei people, and Qiu people. The craftsmen who dyed were: Painter, Jiren, Zhong, Basket, and Arashi. The craftsmen who scrape the Mo are: jade people, nut people, carving people, arrow people, and chimes. The craftsmen who make utensils from clay are: pottery people, 瓬 (fǎng) people.

The Yu clan respects and respects the production of pottery, the Xia Hou clan respects and respects the construction of palaces and ditches, the Yin people respect and respect the production of utensils, and the Zhou people respect and respect the manufacture of vehicles. If it is necessary to gather several types of work to make one type of utensil, the type of work that is gathered by making a car is the largest. The car has 6 parameters: the rear beam is 4 feet high, which is the first class; The Golian handle was 6 feet 6 inches long, and it was inserted into the car and let it recline, 4 feet higher than the crossbar around the bottom of the trunk, which was second-class. The man is 8 feet long, and he stands 4 feet taller than Ge in the car, which is the third class; 殳 (shū) is 12 feet long, and is 4 feet taller than a person when inserted into a car, which is the fourth class; The halberd inserted in the car is 1 constant in length, and it is 4 feet higher than the halberd inserted in the car, which is the fifth class; The chieftain's spear was 1 and 4 feet long, and it was 4 feet higher than the halberd when inserted into the cart, which was the 6th class. Therefore, it is said that the car has 6 and other parameters.

The key to observing a car must start from the part where the car hits the ground, so observing the car must start from the wheels. Observe the essentials of the car, the wheels should be solid in structure, and the contact surface with the ground should be small. If the structure is not strong, it cannot be durable; The contact surface with the ground is not small, so it cannot be fast. If the wheels are too high, it will be inconvenient for people to board the car; If the wheels are too low, it will often be as difficult for the horse as to climb a hill. Therefore, the wheels of military vehicles are 6 feet 6 inches high, the wheels of field vehicles are 6 feet 3 inches high, and the wheels of vehicles are 6 feet 6 inches high. The wheels are 6 feet 6 inches high, the axle end is 3 feet 3 inches high, and the crossbar around the bottom of the trunk and the wooden block between the trunk and the axle are 4 feet. The height of the person is 8 feet, which is used as a convenient knot for people to go up and down.

(2) wheel person / 輈 (zhōu) person

The wheel man makes the wheel, and the three types of wood that are used as the center of the wheel, the straight strip that connects the rim (wǎng) and the hub (gǔ), and the outer periphery of the wheel must be according to a certain season. Once the three types of wood are available, ingenious craftsmen combine them to form wheels. The log in the center of the wheel needs to be conducive to the rotation of the wheel; The straight bar connecting the rim and the hub needs to point directly to the outer circumference of the wheel; The outer circumference of the wheel, which needs to be held securely. Even if the wheel is damaged, the log in the center of the wheel, the straight bar connecting the rim and the hub, and the outer circumference of the wheel are not loose and deformed, so that it can be called perfect.

Looking at the outer periphery of the wheel from a distance, it should be able to slope evenly from the middle to both sides; When you look closer, look at the small size of the land: there is nothing else to emulate here, only the effective circle can do it. From a distance, the straight strip connecting the rim and the hub should be shaved to a smaller end towards the outer circumference of the wheel; On closer inspection, the thickness of each straight bar should be very uniform: there is nothing else to imitate here, only to take the method from the straight.
