Zhāng Hào 張浩 (fl. late 16th c.). Of Héngjùn 恆郡 (modern Zhèngdìng 正定 prefecture, central Héběi). Late-Ming physician with documented Daoist physiological-cultivation interests. Author of the Rénshù biànlǎn 仁術便覽 (KR3ed040), 4 juǎn, completed c. 1585. His Confucian-Daoist medical synthesis places him in the late-Ming Daoist-medical milieu that also produced Yīxué rùmén (Lǐ Chān 李梃, 1575) and Lèijīng (Zhāng Jièbīn, 1624). Not in CBDB; no other biographical record outside his own work and the preface by his kinsman / colleague Zhōu Jiǔgāo 周九皋. Multiple Ming physicians named Zhāng Hào exist in popular medical anthologies; the specific Héngjùn Zhāng Hào is distinguished by the Rénshù biànlǎn attribution and the 1585 date.
