Bì Zìyán 畢自嚴 (1569–1638), zì Jǐngzēng 景曾, hào Báiyáng 白陽, was a late-Míng senior official from Zīchuān 淄川 (Shāndōng). He passed the jìnshì in Wànlì rénchén 萬曆壬辰 = 1592 and rose to Hùbù shàngshū 戶部尚書 (Minister of Revenue) during the Chóngzhēn reign — the office he held for the longest single tenure (about six years) at the height of the dynasty’s fiscal crisis, with the Manchu pressure on the northern frontier escalating and the eunuch / Dōnglín factional struggle still active inside the capital. He is remembered for his exceptional facility with practical revenue matters: contemporaries (e.g. Gāo Héng 高珩 in the preface to the Shíyǐnyuán cánggǎo KR4e0227) record that he handled the dozens of daily fiscal edicts of the wartime Chóngzhēn period in person rather than delegating to subordinates. His main biography is in Míng shǐ j. 256. CBDB 34745.
