Its exquisite carving craftsmanship and profound cultural connotation have been designated as a national first-class cultural relic, and it is a first-class national cultural relic. The grading standards for the stone carvings make it a national treasure. The door pillow stone is a whole piece of bluestone carved in three layers. The top layer is carved with male and female lying lions. The second layer uses a protruding carving technique to carve out a set of character stories with profound educational significance. What's even more wonderful is that this set of patterns complements the couplets on the door. This is a couplet from Liu Yunan, the censor of the Qing Dynasty. The first couplet is: "There is no other way to do things than to do good." We all know that "filial piety is the first, and filial piety is based on kindness." Therefore, the front of the door pillow stone is carved It is a picture of "respecting the old and loving the young". Carved on the inside is a picture of "harmony between sisters-in-law" and "a hidden family and everything is prosperous". The second line is "To pass down a good family, it is better to study." As the saying goes, "Everything is inferior, only studying is high." Therefore, correspondingly, a picture of "apprenticeship and study" was carved. The third layer is engraved with a set of traditional Chinese patterns. The front is engraved with "Phoenix Peony", which implies prosperity and wealth; the inner side is engraved with "Kilin Sending Children" and "Golden Rooster crowing at dawn". By carving this content on the door pillow stone, the Kang family allows future generations to see it when they come in and out. They must also practice it, strictly demand themselves, work conscientiously, and work hard for the revitalization of the Kang family.
