Yang Jie (1889— 1949), a Bai nationality from Dali, Yunnan. Geng Guang, a famous strategist in the Republic of China, was called three and a half chief of staff of China by foreigners together with Jiang Baili, Bai Chongxi and Liu Fei. He was born in Yunnan Army, and later gave up the rank of Lieutenant General to study in Japanese Army University. After graduation, he became Chiang Kai-shek's aide, helped Chiang Kai-shek win the decisive victory in the Central Plains War in the melee of the new warlords, withdrew from the central government because of the conflict with the anti-Japanese strategy, and became the education director of the Army University and the ambassador to the Soviet Union. His new theory of national defense, military and national defense. 1949 was assassinated by Chiang Kai-shek himself because he was prone to revolution and outspoken. We all know that there were three and a half famous military strategists in the military field of the Republic of China. In fact, here refers to four people, three of whom are Jiang Baili, Yang Jie and Bai Chongxi, while the other half may refer to Liu Wen, because this statement is different. Speaking of those three people, maybe everyone knows a little about Bai Chongxi, but the two who can rank in front of Bai Chongxi must be very powerful, so today we will introduce Yang Jie, who ranks second among the three. Yang Jie is from Dali. Yang Jie and Chiang Kai-shek were classmates at the Japanese Army Officers Preparatory School, but they took different paths. At that time, Yang Jie did better in school than Chiang Kai-shek, so two years later, Chiang Kai-shek went to the army and he continued to study in the military school. After returning home, Yang Jie became a guest of honor of warlords from all walks of life, so she also witnessed the disadvantages of warlords from all over the world and felt very confused and helpless. 192 1 year, he took a group of students to study in Japan. After going to Japan, he taught his students not only to come here to learn knowledge, but also to always remember their own country and rush to the motherland when it is needed. 193 1 February, 2008, Yang Jie was appointed president of the Army University. At that time, students from Huangpu reached a certain level before they were sent to the Army University. Therefore, it is conceivable that the military academy must be an excellent student from Huangpu, so the army university at that time was very powerful. 1933, the government of the Republic of China sent a military investigation team to Europe, headed by Yang Jie. Moreover, he became a guest of honor of heads of state and had a good talk with them. He was also called a "strategic expert" by Stalin. After returning home, he contacted Chiang Kai-shek to focus on the development of national defense industry, but Chiang Kai-shek had other plans and did not listen to his advice. Although Yang Jie is very talented, he has a quick temper and offended many people, so he has never been reused. Even Chiang Kai-shek doesn't care about him at all. People like him are doomed to no good results. Finally, he was assassinated by Mao Renfeng in 1949 at the age of 60.
