Earlier, when Japan invaded China with the Western powers, it already valued the resources of northeast China, and for a long time it sent troops to the northeast to try to encroach on China little by little from the northeast. Northeast China also became a springboard for Japan to invade and occupy China, and it was not until the end of World War II that northeast China was liberated.

During japan's occupation of the northeast, it was indispensable to deal with Zhang Zuolin, the king of the northeast, and also helped Zhang Zuolin resist the crusades of the Nationalist government many times, but Zhang Zuolin was a jackal, and Japan wanted to train him into a puppet to control the northeast, which was completely a fool's dream.
Japan is also aware of such a problem, and finally directly tears up zhang Zuolin's face and puts his ambition naked on the table, but Zhang Zuolin is a lord who eats soft and does not eat hard, and Japan has no choice but to kill the killer. Next, we will reproduce the whole process of the Huanggutun incident to you through a set of old photos, which can only be said to be heavy casualties, and finally Zhang Zuolin was carried to the car by his subordinates.
Responsible for the assassination was carried out by the top brass of the Japanese Kwantung Army, who used the spy Yoshiko Kawashima to find out Zhang Zuolin's itinerary, and then planted a bomb at the Sandong Bridge, waiting for Zhang Zuolin's train from Beijing back to Huanggutun in the northeast, aiming to completely make Zhang Zuolin disappear through this explosion.
The Three-Hole Bridge is the only way for Zhang Zuolin to return to the Eastern Emperor Gutun because it is the intersection of the two railways, and the reason why Japan has set the location here is to prevent any accidents, because once the assassination fails, it is bound to be counterattacked by Zhang Zuolin's madness, which will only bring more pressure to Japan, and even cause serious injuries to the yuanqi. For example, in the picture below, there are no Japanese soldiers on the nearby broken bridge watching the hilarity, as if the whole incident has nothing to do with them.
Of course, there is no problem with the intelligence, although Zhang Zuolin made some small actions to hide people's ears, but unfortunately they were all seen by the Kwantung Army, and finally when the train drove through the Three Bridges Cave, the Japanese army detonated the bomb at the first time, and Zhang Zuolin was naturally doomed under such an impact.
In this explosion, a large number of Zhang Zuolin's cronies died, but the Kwantung Army was very cautious, and sent a large number of soldiers to search for it at the end of the explosion, and it was necessary to see Zhang Zuolin's body in order to feel at ease, from here we can also see that the Kwantung Army is full of fear for Zhang Zuolin.
The impact of the explosion caused the train to be invaded by the fire, and after a long period of flame baking, many of the carriages were only left with iron frames, and most of the people were burned to death by the fire because they missed the best rescue time, and even if they survived, they were all covered with scars.
This incident caused the whole world to explode, but no one in Japan at that time dared to stand up and admit it, but everyone tacitly agreed that in this Huanggutun incident, nearly a hundred people were killed and injured, which can be described as extremely painful, and all this was because of Japan's selfish desires.
Zhang Zuolin was seriously injured in this explosion, and when he was found, he was unconscious, or his subordinates carried him off the car, and finally returned to the northeast with his last breath to rescue him, but unfortunately he still lacked skills, and a generation of tyrants withdrew from the stage of history, and the northeast that lost the main heart was subsequently occupied by Japan.
