During the Northeast Anti-Japanese United Army period, a famous anti-Japanese army, Cui Er Kuazi's unit, learned that the Japanese were excavating Huang Taiji's mausoleum illegally, so they led their brothers through thousands of difficulties and dangers, and finally successfully stopped the Japanese action.
In order to protect national cultural relics, Cui Er Kuazi and others transferred all the treasures in the mausoleum. But when they removed the gold mask on the face of Huang Taiji's remains, they found that there was actually a hole in the middle of the forehead above the eyes of the skull, which was the so-called "heavenly eye", and Cui Er Kuazi was greatly shocked. At the same time, they also found that this tomb did not seem like an emperor's mausoleum!
