Zhènchéng 鎮澄 (1547–1617), known by the appellations Yuèchuān 月川 and Kōngyìn 空印, late-Ming Chinese Buddhist monk and Mādhyamaka-school polemicist. He was a contemporary of 德清 Hānshān Déqīng 憨山德清 (1546–1623) and one of the principal figures in the late-Ming doctrinal-polemical controversy over the interpretation of Sēngzhào’s Wù bù qiān lùn (the second treatise of the Zhàolùn, KR6m0038 T1858).

Zhènchéng’s principal work, KR6m0048 Wù bù qiān zhèngliàng lùn 物不遷正量論 (X879), argues that Sēngzhào’s doctrine of “things do not shift” (wù bù qiān) — read as the doctrine that “each thing remains in its position” (wù gè xìngzhù 物各性住) — is doctrinally unsound, since it amounts to a substantialist reading of dharmas and contradicts the Mahāyāna doctrine of intrinsic emptiness (xìngkōng 性空 = bùqiān “non-shifting”). The polemic generated a cluster of late-Ming responses: KR6m0047 X878 by 道衡 Dàohéng (defending Sēngzhào against Zhènchéng) and KR6m0049 X880 by 真界 Zhēnjiè (offering a mediating position).

Zhènchéng was a doctrinal-rigourist Mādhyamaka master in the late-Ming intellectual tradition that included the Three Houses of late-Ming Buddhism. His broader output included sub-commentaries on the Lánkāvatāra, the Awakening of Faith, and the Yogācāra corpus.
