When was the slogan "Party discipline as iron as iron, military order as strong as mountains" proposed?

The source of military orders like mountains: Chapter 49 of "The Romance of the Three Kingdoms" by Luo Guanzhong of the Ming Dynasty: "Yun Chang said: 'I would like to follow the military law.' Kongming said: 'In this way, we will establish a document.' Yun Chang agreed. Military Order."

Example: Chapter 22 of Volume 2 of Yao Xueyin's "Li Zicheng": "You only know that Diao Mingzhong came to Xiangyang to visit his mother, which is understandable, but you forget that military orders are like mountains. Those who disobey the constraints will be executed without mercy."

As for the slogan "Party discipline is like iron, military orders are like mountains", it was proposed in modern times. After all, the party is a product of modern times. It was first hung in the major military camps of the Kuomintang. Whampoa Military Academy also exists. Later, it was gradually changed to "military discipline is iron". Maybe they are afraid that everyone will regard the discipline of the Kuomintang as iron!

Dear, you have to have historical data to prove it. It’s hard to find out who made the suggestion on the roadside.

Personally, I think it was proposed by the Kuomintang for the first time. It was proposed by Sun Yat-sen before the Northern Expedition. The purpose is to force the Communist Party to obey the Kuomintang. After all, Song Zhongshan was somewhat helpless in cooperating with the Communist Party. He once clearly told representatives of the Communist International: "Since the Communist Party joins the Kuomintang, it should obey party discipline and should not openly criticize the Kuomintang. If the Communist Party does not obey the Kuomintang, I will expel them; If Soviet Russia supports the Communist Party of China, I will oppose Soviet Russia. "This can only go so far. Dear, take a look.
