years of the Northern Song Dynasty, Song Taizu Zhao Kuangyin learned from the lessons of the Tang Dynasty middle and late periods and the Five Dynasties and the Ten Kingdoms to prevent the separatist situation of vassal states from happening again, strengthening centralization, emphasizing culture and suppressing military affairs, and the central government finances support the elite army. However, as the number of troops becomes increasingly large, the finances are difficult to support, so the army is allowed to do business, which not only reduces fiscal expenditures, but also ensures the stability of the army. However, as time goes by, the army has begun to compete with the people for profit, affecting the development of civil commerce among the Northern Song Dynasty, and later it has developed into a situation of "redundant soldiers". The army only cares about doing business and has no combat power, which laid the foreshadowing for the demise of the Northern Song Dynasty in the future.
High-level Qing Dynasty , Eight Banners and Green Camp successively "destroyed their own martial arts" and took empty salaries, which forced the Qing court to allow local governments to set up regiment training to ensure the strength of the army.
During the Republic of China, the major warlords acted independently, did not pay attention to the principle of justice, fought against each other, used special power, controlled the local area, oppressed the people at home, and sold out national interests, which made the country always in a state of turmoil and storm, and the people were even more miserable. I wonder if I could see the sun of tomorrow.

It is the countless bloody lessons in history that I have the courage to make up my mind and have today’s rebirth in the fire of the ashes
