During the two years that Huang Yucheng served as a cavalry instructor at the Jiangwu Hall, he organized and compiled textbooks such as "Cavalry Training and Tactics" and "War Horses are Cavalry's Partners." At that time, the new cavalry was crucial to improving the army's mobility and winning by surprise. Because he focused on his work, 27-year-old Huang Yucheng never got married. His parents sent him many messages asking him to go home to get married, but he refused to return with excuses. He always used the famous saying of the Han Dynasty general Huo Qubing, "If you fail to achieve success, you will have no home." The motto is to stay and eat with students, spread revolutionary ideas secretly, and develop members of the Tongmenghui.

At this time in Kunming, new trends were gradually increasing, various new types of education were emerging, private newspapers appeared one after another, and the revolutionary publication "Yunnan Magazine" was secretly spread among soldiers and students. On October 10, 1911, the Wuchang Uprising broke out, which greatly shocked Yunnan. Officers with revolutionary aspirations at the middle and lower levels held several meetings to discuss the uprising. At the same time, they also relied on the Ge Laohui organization among the soldiers to mobilize the majority of soldiers, and finally decided The uprising was launched on October 31, 1911 (the ninth day of the ninth lunar month). On the evening of October 30, Seventy-three Biao stationed at the Beiyang Training Ground was discovered by Beiyang officers for carrying bullets. Platoon leader Huang Yuying and others led the rebel soldiers to kill him, firing the first shot of the Chongjiu Uprising in advance. Huang Yuying led a platoon of leading soldiers to capture the north gate and attack Wuhua Mountain, but was blocked by the Ordnance Bureau, which had a large blockhouse built in the north of the mountain. There is a large amount of ordnance and ammunition stored here. It is a city within a city. The rebel army has few bullets and heavy weapons, and cannot attack for a long time. Platoon leader Wen Hongkui was killed by dozens of bullets. Huang Yucheng took the lead, carrying the light machine gun used for teaching in the martial arts hall, and used firepower to cover the charge. While attracting the enemy's artillery fire, he eliminated the enemy's effective forces. The fierce battle left six bullet holes in his uniform. This military uniform has been kept in the cabinet of Huangzhai's living room and is still there today.

At this time, the 74 Biao commanded by Cai E, Tang Jiyao, and Luo Peijin in the south had not yet entered the city. The insurgents in the north had run out of ammunition and the enemy did not dare to come out. The two sides formed a stalemate. Huang Yucheng and Gu Pinzhen were ordered to lead the Pegasus team straight to the south to the south to recruit troops. Huang Yucheng rode a big green horse that he trained personally and took the lead. When they arrived at Tangzi Alley outside Nancheng, the guarding Qing cavalry shouted: "Whoever dares to rebel will be killed under the orders of the governor!" To go to Nanjiaochang, this is the shortest way, and you must rush over. Huang Yucheng yelled: "Get out of the way, I want to see you Biaotong! Brothers, rush over with me!" He raised his sword and leapt into the enemy formation, swiping his sword to chop several people in succession. In the darkness, only the faint light and shadow of the sword could be seen. Huang Yucheng His military trousers were scratched and his calf was injured. In the critical moment, the big green horse was stabbed in the buttocks. It was frightened and jumped up and ran westward. After getting rid of the enemy, it ran all the way across Jinbi Road and turned to Da Nancheng. The horse's head hit the city wall before stopping. These scenes were all described by General Huang Yucheng himself to his descendants.

Fortunately, Da Nancheng has been occupied by rebel artillery. After passing the code, Huang Yucheng went up to the city tower to meet Liu Yunfeng, the artillery battalion commander and old classmate: "Hurry up and support the northern troops!" However, the artillery distance in the north of Wuhua Mountain was not enough, so Liu and Huang immediately decided to fire at the Governor's Office. Liu Yunfeng personally measured the range and used the light of the flare to target the two big cypress trees at the gate of the Supervisory Office. He shot three times and hit three hits. Governor Li Jingxi was so frightened that he got up from under the bed, sent troops to dig through the walls, hid in people's homes, and ordered the guards to resist desperately. Afterwards, the Ordnance Bureau and the Governor's Office were captured by the rebels respectively. The sound of gunfire that had been ringing all night gradually subsided, and in the early morning, there was only the sound of the footsteps of soldiers running on the street. The people in Kunming couldn't contain their excitement and watched from the cracks in the doors and windows. The brave ones were already following the team and ready to help. Just behind Wuhua Mountain, in an alley below the Ordnance Bureau's gun tower, the gate of a low courtyard opened gently. A middle-aged woman held up a wind lantern and took two girls with her, asking eagerly: "Army "Master, are we going to attack the Qing Dynasty and kill the Tatars?" "Go back quickly, it's dangerous!" a soldier replied. "Hurry and get the bag of pancakes wrapped in a steamed handkerchief on the stove!" The eldest daughter ran to get their family's food for the day. The woman forced the bag of pancakes into the waist of an officer holding a pistol. The youngest daughter is fourteen years old, and she will always remember this night - after that, she became the wife of General Huang Yucheng.

"The Qing Dynasty has returned to the West! There will be no emperor anymore! The uprising was successful! The Republic of China was established! Equalize land rights!" People who had been anxious all night took to the streets of Kunming to set off firecrackers, and slogans kept coming. At the same time, the rebel army headquarters moved to Wuhua Mountain and a provisional military government was established.
