Antiques can be roughly divided into six categories: bronzes, ceramics, calligraphy and painting, jewelry and jade, antique furniture and miscellaneous items. In addition to bronzes, ceramics, calligraphy and painting, the other three categories can be said to be all-encompassing. Antiques include ancient buildings and fossils. It is used for archaeological research in history, culture, customs, and academics.

Antiques are not more valuable as they get older, but their value depends on the quantity, material, the difficulty of preservation, the exquisiteness of objects, the reputation of the original author and so on. There is a saying: scarcity is the most valuable thing. A rare thing, especially an orphan, is definitely worth a lot more than similar things that exist in large quantities. As the saying goes, a penny is worth a penny, and the price of fine products is definitely higher than that of crude products; And celebrity production is definitely more expensive than ordinary craftsmen. Therefore, we cannot generalize.
