Old jars in rural areas, especially those with special historical background or unique craftsmanship, are of high value. Old jars are the product of some traditional rural wine-making techniques, which are generally made of ceramics or mud. These jars are not only used to store and ferment wine, but also have unique shapes and exquisite patterns. As time goes by, the older the old jars, the higher their value, because they represent the inheritance of traditional crafts and history and culture. The ancestral altar is an altar handed down by some rural families and has special historical and cultural value. These jars are handed down by the elders in the family, representing family history and traditional crafts. Such an old jar will become a collection or souvenir, and its value depends on the historical background of the family and the uniqueness of traditional crafts. Some antique jars will be found in the countryside, which are made by ancient ceramic artists and have high artistic and historical value. The value of these antique jars depends on their age, craftsmanship and preservation. Antique jars are unique in shape, exquisite in craftsmanship and precious in historical background, which may be of high value in the collection market.
