​234 Ch'ên Mêng-lei 陳夢雷. 17th and 18th cent. A.D. A scholar who flourished under the reign of the Emperor K'ang Hsi, and took a leading part in the preparation of the great encyclopædia known as the 圖書集成. No sooner, however, had Yung Chêng acceded to the throne than Ch'ên and his son were banished to the frontier, on the ground that the former had been mixed up in the rebellion of Kêng Ching-chung in 1674, and that although pardoned by the late Emperor, he had committed further acts of lawlessness and disloyalty. The continuation of the work was thereupon entrusted to Chiang T'ing-hsi.
