彌堅堂主人 (Mí Jiān Táng Zhǔrén, “Master of the Míjiān Hall”) is the studio-style pen name used by the author of the Qīng romance novel KR4k0291 Zhōng Xū Mèng 終須夢. No other biographical details are known. The pseudonym is formed on the common model of a hall or studio name followed by 主人 (“master/proprietor”), a convention widespread among Qīng popular fiction authors who wished to preserve anonymity. The internal evidence of the novel — the Fujian setting, detailed references to the Zhangzhou 漳州 region, and familiarity with local religious customs — suggests a possible Fujian connection, but this cannot be confirmed. No CBDB entry has been located for this pseudonym.
