The headdress is an important costume for the ruling class to show the hierarchy and the individual to show the identity and personality in ancient China, it is also a mirror of the social customs of an area. In the Ming Dynasty, the Jiangnan area, the key of national economy and culture, witnessed prosperous textile manufacturing and trade. In addition, the Ming Dynasty attached great importance to the compilation of local chronicles, and chronicle cultivation was flourishing, with comprehensive content and obvious regional characteristics. Through the analysis of the local chronicles of the Jiangnan area in the Ming Dynasty, we find that there are differences and contradictory records in the starting time of the luxury custom of the headdress, as well as the phenomenon of repeated changes of customs in some areas. We discuss the causes and influencing factors of these phenomena, and find the changes in headdress customs in the Jiangnan area in the Ming Dynasty recorded in local chronicles were mainly reflected in three aspects. First, the material of the headdress changed from thrift one to luxury one. Second, the ritual system embodied by the headdress gradually developed from following the ritual system in the early Ming Dynasty to the identity confusion in the late Ming Dynasty. Third, the custom of headdress was also manifested in the uncertainty of customs in the same area over time, and there were conflicts in the records of different local chronicles about the time of customs change. We argue that in addition to economic and political factors, the above phenomena were also affected by three factors: social fashion, regional development and local chronicles characteristics. First, the life of citizens in the Jiangnan area in the Ming Dynasty gradually became richer, and the types of clothing and textiles increased, which was embodied in the improvement of clothing shapes, the increase in the types and colors of fabrics, so the luxury customs of clothing recorded in local chronicles partly stemmed from people's pursuit of fashion trends, which was seeking "newness" rather than "luxury". Second, during this period, the gap between the rich and the poor was large. In the middle and late Ming Dynasty, there was an unbalanced development between areas, and some areas were not affected by the luxury atmosphere. Customs varied widely in the same area, which resulted in inconsistent customs records in different local chronicles. Third, as official documents, local chronicles have the function of educating the people and reflect the political achievements of local officials. Therefore, some bad social atmospheres would be appropriately hidden in the records, and the good parts would be highlighted. These human factors interfered with the local chronicle's record of the real situation, resulting in the erroneous phenomenon of headdress custom records. We summarize the clothing customs represented by the headdress in the local chronicles of the Jiangnan area in the Ming Dynasty. Combining with the documents in the same period, we generalize its development law and point out the omissions. Moreover, we discuss the customs, fashion, clothing concept, regional development, etc. of the Jiangnan area in the Ming Dynasty, as well as the influence of the particularity of local chronicles on the records of clothing customs. We try to discover the role of costumes in the historical evolution from local historical materials, hoping to provide a new perspective for regional research on costumes. [ABSTRACT FROM AUTHOR]
