Dagui Zhengzhang (b. 1304), styled Hengbai and known as Da'gui ('Great Jade Tablet'), was a Yuan-dynasty Linji/Yangqi master from Jinjiang in Fujian. He awakened under Dongyu Dehai on hearing his verse on Juzhi's raised finger, and later taught at Ziyun temple in Quanzhou and at Doufeng in Jianning, where he died. A noted literary monk, he left the Mengguan ji (夢觀集) and the Kaishi zhuan; the Siku catalogue praises his poetry as 'bold-boned'.
