Identifying a collection is not only to identify its authenticity, but also to identify which dynasty it belongs to, how many dynasties it has experienced, what level of influence it had in that era, and which famous teacher it came from, and to classify it.
Collection identification method ① Classification: During identification, items can be classified according to the characteristics of different dynasties or according to their production methods. Then find out the similarities and differences between the collections in the same category.
② Comparison: compare the newly unearthed unrecognizable ancient cultural relics with the collections with exact age, place of origin, author, production method and appearance characteristics, see the similarities and differences between the collections and standard cultural relics, and identify their authenticity and historical background.
Appraisal: When a collection cannot be appraised, appraisers can discuss and communicate with each other, which will always be closer to the truth.
