Biography
Zhang was a member of the Honghuzi irregular cavalry forces of the Manchurian warlord Feng Delin during the First Sino-Japanese War. These forces were recruited as mercenaries by the Japanese during the Russo-Japanese War of 1904-1904. He subsequently studied at the Northeast Military Academy built by General Zhao Erxun. Following the Xinhai Revolution, he was assigned command of an infantry regiment under the Republic of China; however, he supported Zhang Xun's abortive attempt to restore the Qing dynasty in 1917. He afterwards joined forces with Manchurian warlord Zhang Zuolin. In 1923, he was appointed a commissioner of the Chinese Eastern Railway and participated in the First Zhili–Fengtian War. in early 1931, his forces were involved in the suppression of the Gada Meiren uprising.

In early October 1931, shortly after the Mukden Incident, at Taonan in the northwest of Liaoning province, Zhang, who was commander of the 2nd Provincial Defense Brigade, took command of the local forces including the Hsingan Reclamation Army and declared the district independent of China, in return for a shipment of a large quantity of military supplies by the Imperial Japanese Army.

Zhang followed his political move up by leading the men of the Hsingan Reclamation Army north to attack General Ma Zhanshan the newly appointed governor of Heilungkiang province. Soon after Zhang advanced upon Ma's capital at Qiqihar, Ma offered to surrender it. Encouraged by Japanese Kwantung Army General Shigeru Honjō, Zhang advanced cautiously to accept General Ma's surrender. However Zhang's advance guard was attacked by Ma's troops in the Resistance at Nenjiang Bridge and it was routed.

Following the establishment of the State of Manchukuo in March 1932, Zhang was reappointed to commanded his old force, which was now renamed the Taoliao Army. He led Manchukouan troops against the Anti-Japanese Volunteer Armies during the Pacification of Manchukuo and in the Japanese invasion of Rehe in Operation Nekka. Afterwards, he was appointed to command the newly organized Rehe Guard Army, which became the 5th District Army "Chengde" after the 1934 reorganization of the Manchukuoan Army. From March 1933 to November 1934, he was Governor of Rehe Province. He was promoted to full general in the Manchukuo Army in 1936. In 1941, he went into retirement.

After the collapse of Manchukuo in 1945, Chang went into hiding in Tianjin, but was discovered and executed for treason by the People's Republic of China in 1949 in Beijing.
