When it comes to the "Principal of the Whampoa Military Academy", most people will think of Chiang Kai-shek. Indeed, the Whampoa Military Academy, as the military capital of Chiang Kai-shek's career, has long been closely tied to his name, and everyone calls him "principal" more than calling him **. However, after all, Chiang Kai-shek was entangled in official duties, and it was difficult for him to have spare energy to take care of the Whampoa Military Academy for a long time, so after him, two people took over the burden of the principal, one was Guan Linzheng and the other was Zhang Yaoming. 
After Chiang Kai-shek stepped down as president, Guan Lin was recruited to replace him, but he was later so disappointed with the old Chiang that he simply went into hiding. Lao Jiang picked and chosen, and finally chose Zhang Yaoming. The reason why Chiang Kai-shek handed over the Whampoa Military Academy to Zhang Yaoming was nothing more than two reasons, the first was that Zhang Yaoming was able to fight well and was a general;Secondly, he followed Chiang Kai-shek for many years, and he can be regarded as loyal. To say that the origin of Zhang Yaoming and Chiang Kai-shek can be traced back to 1924, when the Whampoa Military Academy was just established, Zhang Yaoming, together with Guan Linzheng and Du Yuming, was admitted to the first phase of Whampoa and became the most trusted "protégé of the Son of Heaven" by Chiang Kai-shek. From the beginning of the Northern Expedition, Zhang Yaoming followed Chiang Kai-shek to fight in the south and the north, which can be described as a great achievement, and he has always been very loyal to Chiang Kai-shek. As early as 1933, in the Beigukou War of Resistance, Zhang Yaoming and Guan Linzheng were the main forces, and they stubbornly blocked the Japanese army outside Shanhaiguan and preserved the dignity of the Chinese. 
After the outbreak of the War of Resistance Against Japanese Aggression, Zhang Yaoming's troops stationed in Baoding were besieged by three divisions of the Japanese army, and the Japanese army also had air superiority and carried out an air raid from time to time. However, they could never have imagined that this "turtle" was far more powerful than they imagined!Zhang Yaoming led the 25th Division, which controlled the position to the death, supported it for two days and two nights, and then took advantage of the slight relaxation of the Japanese army and successfully broke through in one go!Moreover, his breakthrough was not a hasty escape, but a full assessment of the situation, random movements, seeing that the Japanese army did not start a pursuit, Zhang Yaoming simply hugged the grass and beat the rabbit, and by the way bombed the Japanese airfield outside Handan. If this is not fierce enough, let's look at the Battle of Taierzhuang. We all know that Li Zongren, Wang Mingzhang and others contributed a lot in the Battle of Taierzhuang, but why didn't Zhang Yaoming do it?In the face of the attacking enemy Isoya Ryosuke's division and the Sakamoto detachment of the Fifth Division, Zhang Yaoming not only did not have the slightest timidity, but changed from passive to active, and ate the cavalry detachment on the opposite side in one bite, which not only dealt a heavy blow to the little Japanese, but also greatly boosted the morale of the army, thus making a good start to the Taierzhuang Campaign. 
In addition, in battles such as the Battle of Changsha and the Battle of Central Henan, Zhang Yaoming played the role of the nightmare of the Japanese army, no wonder some people commented that he was the "nemesis of the Japanese army". can fight and be loyal, how can he not be trusted by Lao Jiang?Although during the Liberation War, Zhang Yaoming's performance was not worth mentioning, but considering that there were really few people in the Kuomintang army who fought well, Lao Jiang did not blame him, but let him serve as the principal of the Whampoa Military Academy to guard his last base camp. However, at this time, Zhang Yaoming had already lost his heart, and after only 3 months, he quit and slipped away alone. Not long after he left, the teachers and students of the Whampoa Military Academy telegraphed to revolt. Although these foolish things he did almost blew up Chiang Kai-shek, fortunately, the old Chiang remembered his past exploits and did not pursue them excessively, but he would definitely not be reused again. Zhang Yaoming himself knew that he had made mistakes, so he didn't complain too much, but cultivated himself at home with peace of mind and lived until 1972.
