LAI-YANG, a city in the Chinese province of Shan-tung, in 37 N., 120 55' E., about the middle of the eastern peninsula, on the highway running south from Chi-fu to Kin-Kia or Tingtsu harbour. It is surrounded by well-kept walls of great antiquity, and its main streets are spanned by large pailous or monumental arches, some dating from the time of the emperor Tai-ting-ti of the Yuan dynasty (1324). There are extensive suburbs both to the north and south, and the total population is estimated at 50,0x20. The so-called Ailanthus silk produced by Saturnia cynthia is woven at Lai-yang into a strong fabric; and the manufacture of the peculiar kind of wax obtained from the la-shu or wax-tree insect is largely carried on in the vicinity.
