The jar is an ancient apparatus for storing alcohol, also known as "jar" and "barrel". They are usually made of wood or ceramics, mostly cylindrical or oval in shape, with different sizes of bottom structures. In ancient times, people often used jars to store rice wine, white wine, yellow wine and other brewed wines. On holidays or family gatherings, the wine in the jar will be taken out to entertain relatives and friends.

Jars are also one of the traditional wedding necessities in China, and are used to entertain relatives and friends. Wedding jars are generally large-scale ceramics, and sometimes they are used to store gifts such as honey wine and candied dates. When the bride gets married in her new house, her mother-in-law or daughter-in-law pours a cup of hot wine to represent celebration and reunion, and wishes the newlyweds a hundred years of harmony.

Nowadays, the altar of wine has become a part of traditional culture, and many artists regard it as a creative theme, which plays an important role in ceramics, calligraphy, painting and other fields. In addition, jars also have practical value in modern life. In hotels or restaurants, jars are often used to provide special drinks for guests, adding rich cultural atmosphere and local customs to restaurants.
