Ordinary old blue bricks and old stone piers in rural areas are not very valuable. Only some blue masonry piers with exquisite patterns and certain historical and cultural values can be regarded as cultural relics. Vendors go to the countryside to buy those old blue bricks, stone piers, stone mills, etc. And their purpose is generally to sell to some people in need. As some nostalgic old objects, they are placed in farmhouses, hotels, theme parks, old tourist houses and collectors' homes, giving people an idea of their past lives. The seller made a profit in this sales process.

Old things are not very valuable. In rural areas, some people often buy old things, including old blue bricks, stone blocks, mangers, stone mills and even some old furniture. In fact, these old things are not necessarily valuable. It can be said that most of them are just people's daily necessities in the past. Although it has a certain age, it can't be called a cultural relic and has little historical and cultural value. At most, it makes modern people look nostalgic and reminds people of the past years. Ordinary people can't sell these old things because no one buys them, but those vendors who come to the countryside to buy them have their own channels. After changing hands, they can make some money from these old things. However, this resale business will not earn much, because these old objects are not cultural relics after all, nor are they old objects left over from the Ming and Qing Dynasties, nor are they old stone tools with superb carving skills. Market factors determine that it cannot be sold at a high price.

Old objects and people's nostalgia With the development of society and the needs of people's spiritual life, many people gradually began to miss old objects, especially the increasingly rare old stones, stone mills and old-fashioned furniture, which can remind people of the past years and remind people of stories and experiences of that era. Therefore, there are many theme parks, services and tourist sites. In order to meet people's psychological needs, they specially buy these old objects as decorations and furnishings to satisfy people's nostalgia and gain the recognition of guests. Obviously, this is a success. When people see these rare old objects, most people are full of admiration. They think that these old objects are meaningful and memorable, which gives birth to such a market and makes these old objects in rural areas useful again.

Ornamental value of old objects I once visited the former residence of a revolutionary. It is an old house, which is filled with ancient waterwheels, rectangular wooden tables, old chairs, stone mills, hemp fiber hats for farmers, enamel cups of that era and so on. At first glance, people are nostalgic and think of the years when they were young. Old objects that are rare for decades are very touching and better than some so-called modern decorations. This is the appreciation value of old things.
