A Chinese Biographical Dictionary/Chang P'ei
93 Chang P'ei 張伾. 8th cent. A.D. An Imperialist officer, famous for his defence of 臨洺 Lin-ming against T'ien Yüeh in 781. When his funds were exhausted and his men starving, he made his daughter appear in full dress before his officers, offering to sell her to procure them a day's pay. Touched by his devotion, they held out until Ma Sui came to their relief, when they inflicted a crushing defeat on the besiegers.
