The third issue of the fourth season of the cultural exploration program "National Treasure" by China Radio and Television Group focuses on the Jiangxi museum module, specifically delving into the national treasure "Blue and White Glaze Red Pavilion Barn with Characters in the Yuan Dynasty · Past Life Legend". According to the epitaph engraved on the barn, the tomb owner Ling, who disguised as a man while studying at Changxiang Academy and met refugees fleeing from famine to Jiangxi on the way home down the hill, decided to come back to Ling' family to open the barn for disaster relief. Finally, Ling and Liu Bingwen got married and rescued victims. Because there is no record of Ling's life except family background, marriage and funeral, the relevant information of Ling's life is supplemented by combing the family pedigree, living area and background of the times. With reference to the costume system and documents of the Yuan Dynasty, according to the image remains of tomb murals, temple murals, scroll paintings of characters, and combined with the physical costumes, concrete analysis and textual research are conducted on the shape, fabric, color, pattern and other aspects of Ling's costume when she disguised as men, and the characteristics and features of the Han men's costume in the Yuan Dynasty are outlined and restored.
