JEHOL (“hot stream”), or Ch’ēng–tē–fu, a city of China, formerly the seat of the emperor’s summer palace, near 118° E. and 41° N., about 140 m. N.E. of Peking, with which it is connected by an excellent road. Pop. (estimate), 10,000. It is a flourishing town, and consists of one great street, about 2 m. long, with smaller streets radiating in all directions. The people are well-to-do and there are some fine shops. The palace, called Pi-shu-shan-chuang, or “mountain lodge for avoiding heat,” was built in 1703 on the plan of the palace of Yuen-ming-yuen near Peking. A substantial brick wall 6 m. in circuit encloses several well-wooded heights and extensive gardens, rockeries, pavilions, temples, &c. Jehol was visited by Lord Macartney on his celebrated mission to the emperor K’ienlung in 1793; and it was to Jehol that the emperor Hienfēng retired when the allied armies of England and France occupied Peking in 1860. In the vicinity of Jehol are numerous Lama monasteries and temples, the most remarkable being Potala-su, built on the model of the palace of the grand lama of Tibet at Potala.
