1992, a maid-in-waiting incident happened on the wall of the Forbidden City. What is the principle of video recording of ferroferric oxide encountering lightning?

The Forbidden City in Beijing is the imperial palace of Ming and Qing Dynasties. Hundreds of years later, there were many concubines, maids and eunuchs who died unjustly in the palace. Therefore, the Forbidden City has always been full of mysterious feelings. Take modern history as an example, there have been incidents in which consorts were forced into wells. So there are many mysterious events in the Forbidden City. 1992, there was a walking maid-in-waiting incident in the Forbidden City, but according to the explanation of scientists, ferroferric oxide can be recorded when it meets lightning, but I don't think these are credible!

First, the Forbidden City, the imperial palace of the Ming and Qing Dynasties, has gone through hundreds of years! As we know, the Forbidden City, the Forbidden City in Beijing, formerly known as the Forbidden City, was the imperial palace of China in the Ming and Qing Dynasties. The Forbidden City in Beijing has a total area of 720,000 square meters and a construction area of 6,543,8+0.5 million square meters. * * * has more than 70 palaces and more than 9,000 houses. Whether in Ming Dynasty, Qing Dynasty or modern times, the lofty social and historical status of the Forbidden City is self-evident. It is not only one of the largest and best-preserved ancient wooden structures in the world, but also a national 5A-level tourist attraction and world cultural heritage.

2. 1992, a maid-in-waiting incident occurred on the wall of the Forbidden City. Scientists explained that ferroferric oxide can be recorded when it meets lightning, which is unbelievable! The main reason why the Forbidden City became popular on the Internet was the maid-in-waiting incident of 1992, which attracted the attention of netizens and made the Forbidden City once a "network celebrity". When this matter was hot, the answer given by scientists was the result of a chemical reaction between ferroferric oxide and lightning. The wall of the Forbidden City in Beijing has always been red, but the wall of the Forbidden City is not a simple wall, it contains a special substance? Ferroferric oxide. In the Qing dynasty, the sky thundered and thundered, and there happened to be maids passing by. In this special climatic condition, the palace wall containing ferroferric oxide is equivalent to having the function of a video tape, recording the walking of ladies-in-waiting in the palace wall as a video.

1992 One day, the Forbidden City welcomed a batch of tourists as always. Suddenly, there was a loud thunder, lightning and thunder, and the whole Forbidden City was suddenly dark. Then a miraculous event appeared, and only a row of maids appeared on the red palace wall. This image preserved in the palace wall was played by coincidence, which shocked the scientific community.

However, although this video has attracted a lot of people's attention, obviously, the statement that ferroferric oxide can be recorded when it meets lightning is not credible! It is said that many tourists saw it, but there is no definite evidence. These photos taken in those years have also been deleted, and the so-called chemical reactions confirmed by scientists are inconclusive.

To sum up, I don't think the 1992 Palace Wall Maid Incident is the rumored paranormal. It is not enough to believe that the palace wall can be videotaped when it encounters chemical reactions. The biggest possibility is that a crew is filming the Qing Palace drama, so a row of maids passed by, which coincided with a thunderstorm, so they were misunderstood as supernatural. What do you think of this matter?
