The September 18 Incident made Zhang Xueliang a sinner for eternity, when Japan launched a war of aggression against China, because Zhang Xueliang's inaction led to the easy occupation of the three eastern provinces by Japan. After the three eastern provinces were occupied by the Japanese army, Zhang Xueliang also regretted it, and Zhang Xueliang said in his heartache that if Guo Songling was still there, the Japanese would not dare to step into Chinese territory.
Let's take a look at Guo Songling's life, stumbling and bumping is very bumpy, often walking on the tip of the knife many times life hanging in the line, in 1917, Guo Songling and put into the Revolutionary Government of Sun Yat-sen Guangdong, a failure Guo Songling had no choice, had to go back to his hometown to hide, and later Zhang Zuolin noticed this person, asked Guo Songling to come to the northeast to teach the Northeast Army, improve the combat effectiveness of the Northeast Army, so that he also knew the young marshal Zhang Xueliang.
In 1922, when the Zhifeng War was fought, a total of 120,000 people in the Northeast Army participated in the war, but only 20,000 people returned in the end, which made Zhang Zuolin very angry. These people were all subordinates of Zhang Xueliang and Guo Songling, so Zhang Zuolin later ordered Guo Songling to become a disarmament review envoy, a position specifically designed to lay off unqualified military units. It was Zhang Changzong who defected to Zhang Zuolin, but Zhang Changzong secretly resold opium for safety, but was discovered by Guo Songling, who insisted on laying off Zhang Changzong and his troops.
Later, the army under the leadership of Guo Songling fought as much as possible, and Zhang Zuolin also appreciated Guo Songling very much, and Zhang Xueliang and Guo Songling had a very good relationship at that time. But it was Zhang Zuolin who changed all this.
In 1925, Zhang Zuolin signed many unequal treaties, Guo Songling was very irritable after hearing about it, so Guo Songling borrowed the orders of the young marshal to send troops, because Guo Songling was extremely talented in leading troops, and Zhang Zuolin was caught off guard by this battle, and zhang Zuolin had no choice but to agree to the Treaty of the Japanese to repel Guo Songling. And Zhang Xueliang did not know the reason, after his father told him the matter, Zhang Xueliang found Guo Songling, originally wanted to solve the problem privately, but Guo Songling strongly opposed, because Zhang Xueliang knew Guo Songling very well, familiar with Guo Songling's way of fighting, Zhang Xueliang easily grasped the military power of Guo Songling's army.
Guo Songling quickly fled after knowing this, but he was still one step too late, and was eventually caught by Zhang Zuolin, but Zhang Xueliang wanted to arrange for Guo Songling to escape on the road out of affection, but Guo Songling was killed by Zhang Zuolin on the spot. A generation of heroes disappeared.
