Chén Niànzǔ 陳念祖 ( Xiūyuán 修園, also Liángyǒu 良有, 1753–1823, CBDB 81917), native of Chánglè 長樂 (modern Fújiàn). He passed the jǔrén exam (Qiánlóng 57 = 1792) and served briefly as Hébǎo zhīxiàn 河北 magistrate before retiring to teach medicine at Fúzhōu.

Chén is the most prolific medical popularizer of the Qiánlóng-Jiāqìng era. His pedagogical output is enormous and his works served as the standard zhōngyī textbooks for two centuries. The principal works are:

  1. Yīxué shí zài yì 醫學實在易 (1808) — accessible introduction to medicine.
  2. Yīxué cóng zhòng lù 醫學從眾錄 — clinical reference.
  3. Shānghán lùn qiǎn zhù 傷寒論淺注 — accessible Shānghán lùn commentary.
  4. Jīnguì yàoluè qiǎn zhù 金匱要略淺注 — companion to (3).
  5. Yī yī ǒu cuì 醫醫偶萃 — collected medical essays.
  6. Niǔ wàn lùn / Nǚ kē yào zhǐ 女科要旨 — gynaecology.
  7. Shénnóng běncǎo jīng dú 神農本草經讀 (KR3ec046) — pharmacological reading.

The collected Xiūyuán quánshū 修園全書 served as the standard physician textbook for two centuries.

CBDB has two Chén Niànzǔ records: 81917 with lifedates 1753–1823 (the relevant entry) and 81918 with 1852–1890 (a different, later figure).

Principal modern edition: Lǐ Lǐ 李力, Chén Xiūyuán yīxué quánshū 陳修園醫學全書 (Renmin weisheng, 2002).
