And during the siege, it can also be used to build siege equipment, such as ladders, etc., to help soldiers climb the city wall and break through the enemy's defense line.
In the construction of fortifications, it is also indispensable. When building bridges, this product is used as a key material to build a stable structure, so that the bridge can carry the weight of vehicles, horses and pedestrians, cross rivers and gullies, and facilitate transportation. The construction of water conservancy facilities, such as dams and sluices, can ensure that the structure of the project is solid, resist the impact of water flow, and protect one side from flood intrusion.
It also plays an important role in daily labor. Farmers build houses and use them as basic materials to build stable dwellings, shelter from wind and rain, and keep their families safe. In mountain forest logging operations, it can be used to build temporary plank roads to facilitate the transportation of wood. In mining sites, this product can build a support structure to ensure the safety of miners' operations, so that the mining work can be carried out in an orderly manner.
In short, this product has shown important application value in many fields such as military, engineering, and people's livelihood, and is indeed indispensable.

The manufacturing method of this item is as follows:
First take the high-quality wood, which needs to be tough and fine in texture. If you want to make wood, choose the genus of red sandalwood and huanghuali. This kind of wood is solid and durable, and has natural beauty.
Then, use a sharp axe to cut its thick shape, remove its branches, and make it first contoured. This step requires the craftsman to be clear-eyed and quick, with the general appearance of the object in his heart, and to start with precision, so that there is no mistake.
Then sawing it, so that the wood size is the same as required. When sawing, the force should be equal, and the direction should be correct, so that the sawed wood can be flat.
Then, use a plane to plane its surface, so that it is as smooth as a mirror. The key to planing is that the planing is smooth, the force is uniform, and there should be no deviation at all, so that the surface can be free from unevenness.
As for the art of carving, it is particularly delicate. Depending on the use and design of the object, or shallow carving of flowers, birds, fish and insects, or deep carving of auspicious beasts' auspicious patterns. When carving, the hand holding the knife is as steady as a rock, and the knife is like a pen. The lines are smooth and natural, and the density is appropriate, so that it can be agile.
If it is a metal utensil, first melt and cast the metal. Choose a good metal, such as gold, silver, copper, etc., put it in a furnace, calcined with fierce fire, and wait for it to turn into golden water, and pour it into a special model. The model needs to be carefully made in advance, according to the shape of the utensil, the gold water enters the mold, and it needs to be cooled and formed.
After forming, the grinding, chiseling and other processes are carried out. Polishing makes the surface of the utensil shiny and radiant, and the chiseling adds exquisite ornaments, or auspicious words, or wishful shapes, all of which add to the charm of the utensil.
All this manufacturing method depends on the exquisite skills of the craftsman, dedication and meticulous, in order to create excellent things.
