Ulmus pumila, Ulmus pumila and Ulmus pumila are mainly produced in temperate zones, deciduous trees and tall trees, which are distributed all over the north, especially in the Yellow River basin. Elm wood is tough, clear in texture, moderate in hardness and strength, suitable for general relief carvings, smooth in plane, beautiful in chord patterns, and "chicken-winged wood" patterns, which can be used for furniture and decoration. After drying, modeling, carving, polishing and painting, elm can be made into exquisite carved lacquer crafts. It can be seen everywhere in the furniture market in the north.
Elms and beeches produced in the south are called "beeches in the north". And the width of the fabric is large, and the texture is moist and excellent; The deformation rate is small, and the carved patterns are mostly rough. This is a great man and a gentleman.
Elm can be divided into yellow elm and purple elm. Elm is more common, and the wood is pale yellow when it is newly cut, and its color gradually deepens with the growth of tree age; Purple elm is naturally dark purple, and the color of heavy elm is similar to that of old mahogany. So the biggest furniture in the north is elm, waxed and painted. Elm is made of other materials, and traces of elm furniture can be seen at any time in Shanxi, Shandong, Hebei, Henan and other ancient furniture provinces. The production time span of elm furniture is very long, and it never stopped from the beginning of Ming Dynasty to the end of Qing Dynasty, and its evolution process and regional characteristics are very clear. Early elm furniture was mainly dedicated to furniture, such as tables and cases, which looked like Gu Zhuo and were mostly displayed in temples, family shrines and other places, so it can be preserved to this day. There is a wooden basin carved from elm, without paint or decoration. After long-term touch and air oxidation, the patina is bright and dazzling, and the wood grain is old and vigorous. A century-old relic, intact, caresses the heart like a crisp. As if touching the vicissitudes of life.
Now there is a saying in the market that white wood can also be collected, referring to elm in the Ming Dynasty and nanmu in the Qing Dynasty. However, due to the beautiful natural grain, tough texture, tall and straight grain, and the unique simple and natural color and charm of elm, it is in line with the concept of being a man respected by the ancients. Therefore, from ancient times to the present, elm is very popular, and it is the first choice for making furniture, from dignitaries and literati to Li people.

Collectors see whether it can preserve its value, mainly in the following aspects. First, the beauty of form and shape of furniture, whether complex or simple, depends on whether it is attractive or not. Second, the material is excellent, and the log material can be preserved for a long time, so the more you use it, the more moist it is. Third, exquisite workmanship, elegance, comeliness and elegance, and good aesthetic intention.
