曽国藩
During the Taiping Rebellion, tuanlian militia was expanded by Zeng Guofan into an army force of thirteen battalions consisted of 6500 men, a navy of ten battalions consisted of 5000 men, of a total of 17,000 men, was given the name of Xiang Army, with Zeng Guofan as the Commander-in-chief, accepting orders from Zeng alone. The new rule was termed "Soldiers followed the general, soldiers belonged to the general"(Chinese: 兵隨將轉，兵為將有), contrary to the old military rule before the Northern Song Dynasty's "Soldiers had no fixed commander, commander had no fixed soldiers" (Chinese:兵無常帥，帥無常兵). This new military rule was the direct cause of the Warlord era. These Tuanlian were turned into the Yong Ying Xiang Army.
