Qiángmíng zǐ 強名子 (“Master of the Forced Name” — a self-ascribed pseudonym alluding to Lǎozǐ ch. 25, qiáng wéi zhī míng yuē Dào 強為之名曰道, “if forced to give it a name, I call it the Way”) was an early-tenth-century Daoist of the Five Dynasties period. According to his own undated preface to Zhēnqì huányuán míng 真氣還元銘 KR5a0276 (DZ 264), during the Zhēnmíng 貞明 reign-period (915–920) of the HòuLiáng 後梁 dynasty he visited Mount Tài 太山 and met an immortal who transmitted to him the “art of spitting out [the old] and inhaling [the new] and perfecting the body” (tǔnà liànxíng 吐納鍊形). The immortal told him not to divulge these secrets before twenty years had passed; in the late 930s, that time having arrived, he worked the instructions into a xīnjīng 新經 (“new scripture”) for inscription on holy mountains. Nothing is known of his actual identity. Schipper-Verellen (2004) 1:369 places the work in the first half of the tenth century.
