Chen greatly admires the Ming dynasty for its emphasis on swords and swordplay. He improved on the one-handed Ming long sword by simplifying and streamlining it, and by combining the best traditional forging techniques with today's most advanced steels and heat treatment processes. He named his sword Vermilion Gate to express his intent to combine nostalgia, preservation, and innovation.
陳天陽愛慕明朝重劍、習劍的風氣，特別改良明制單手長劍，使之更簡潔、線條更流暢，再搭配傳統鍛打工藝與現代最新的熱處理科技，結合精良鋼材，最後將劍定名為「朱門」，以表示懷古、薪傳與開創的結合。
