This lot has been preserved in natural storage and features a thicker body along with a special "中" character on the packaging. Using the 7682 formula, it represents the last batch produced by the Menghai Tea Factory with antique tea leaves and was one of the first to employ experimental fermentation techniques. The tea cakes exhibit notes of camphor and medicinal aromas, suggesting potential for further aging transformation.
