[1] Zhang returned home on 21 December of that same year and entered a church hall one morning in order to pray alone.
The following year after closely studying the Seventh-day Adventist doctrines, he subsequently changed his Sabbath services to Saturdays instead of Sunday.
During 1913 and 1914 Ling-Sheng began forming the "True Jesus Church" and held services at his home with friends and relatives.
In 1917 Ling-Sheng went to the Church of God in Beijing and there he met an American missionary named Berntsen who also kept the Sabbath on Saturdays and whom preached on issues concerning the baptism of the Holy Spirit.
In the Spring of 1918, Ling-sheng started preaching the gospel of the True Jesus Church in co-operation with Paul Wei, another co-worker.
