The production process of a certain product is particularly exquisite, and in terms of ancient methods, it is quite ingenious.
First take the best materials, this is the foundation. Materials must be carefully selected, and those with firm texture and pure color should be included. For example, when making utensils, wood should be selected with straight texture, no knots and no scars, and stone should be selected with delicate texture and warm jade. If the selection of materials is not careful, even if there is good workmanship, it will not be a good product.
When you have obtained good materials, you will enter the process of carving. The craftsman holds exquisite tools, and according to the shape of his heart, the catty will become the wind. At the beginning, he made a big deal, cut off the excess, and set its rough outline, just like Pangu opened the sky, and the chaos was first divided. Then, carefully carve and carve, and see the kung fu in the slightest. The carved birds are lifelike, as if they want to flutter their wings and fly, and chirp tactfully; the engraved characters have a good demeanor, or kind-hearted eyes, or heroic. This skill is not the work of accumulating years and months, and the corresponding ingenuity of the heart and hand cannot be done.
In the meantime, the grasp of heat and strength is crucial. If the heat is too prosperous, the material is easy to char and crack; if the strength is uneven, the shape will be inaccurate. The craftsman relies on years of experience, such as blister Ding to solve the cow, it is imperfect, and the mind understands it. Touch it with the hand, listen to it with the ear, and feel it with the heart, it can be just right.
And between the processes, the connection is close, interlocking. The previous process is not perfect, and you must not rashly enter the next journey. Every step is like walking on thin ice, with a slight mistake, and the whole game is lost.
To be carved, it is still polished and modified. With delicate objects, wipe and slowly grind, so that the surface is smooth like a mirror, and the texture is warm. This is the finishing touch, which can make the utensils glow with a different brilliance, like pearls that are dusty and then regain their radiance.
After these various processes, a beautiful product can be produced. It embodies the efforts of countless craftsmen and also highlights the breadth and depth of traditional craftsmanship. It is a rare treasure in the world.

Today, when we look at the products in the market, the analysis of their competitiveness can be compared to the ancient weighing of all things. The city is like a battlefield, and the products are like soldiers. If you want to show your ability, you must have unique advantages.
First of all, it should have extraordinary quality. Gu Yun: "If you want to be good at your work, you must first sharpen your tools." The quality of the product, if the tool is dull, is related to the root. Quality is like a good sword, cutting thorns and shawls, which can win the hearts of the people and establish the foundation of the city. Like a well-crafted beautiful jade, which is warm and lustrous, everyone loves it, and if it is placed in the market, there will be many buyers. If the product is of high quality, sturdy and durable, and has excellent functions, it will be different from ordinary products, and it will emerge.
Second, it needs to be in time. The world changes and the times change, and the needs of people also change. Products should observe the world's conditions, understand people's desires, and apply medicine to the symptoms of a good doctor. The wise of ancient times can achieve great things by adapting to the times. Today's products, if they can be born in response to the times and solve the difficulties of everyone, like the breeze on a summer day and the rain in a dry time, their city will be wide. Just like the slow cars and horses in the past, and then the rise of steamboats and trains, they will all meet the needs of the times. If this product fits the needs of people's lives and work today, it will definitely win the favor of the city.
Furthermore, the reputation is also important. "People cannot stand without trust", and the same is true for products. A good reputation is passed down in the city, like the fragrance of flowers, and everyone hears it. Those who have a good reputation believe it and are willing to pass on their name. In the past, Meng tasted the wisdom, which was famous all over the world, and everyone respected it. If the product has a good reputation, the quality is reliable, and the service is meticulous, the buyer will pass it on by mouth, attracting more people, and the competitiveness of the city will rise.
There is also a way of marketing. The merchants of ancient times are good at publicizing their goods. Today's products should also be promoted. Or borrow the power of various media, or hold various exhibitions, so that everyone can know its beauty. Such as the ancient hanging flag in the city, attracting attention, today's network publicity, wide dissemination of information, so that the name of the product is far and wide, more and more buyers, stronger competitiveness.
In summary, products in the city, with high quality, timely needs, good reputation, good marketing, strong competitiveness, can ride the wind and waves in the tide of the city, long-term foothold.
