My name is Chen Gaoran, and I am a special photojournalist for this city's Metropolis Evening News. I came to Beijing by a special opportunity because a Qing Dynasty mausoleum was recently discovered in Beijing. It was located in a dangerous location and was buried 100 meters deep. So before it was discovered, the most amazing thing was that there was only a set of official uniforms of a Qing Dynasty prince and a round glass mirror in the coffin. At that time, there was no technology in the world to produce such modern glass products, but it has been verified by many archaeologists and historians. This official uniform and mirror indeed come from the 40th to 60th year of Kangxi's reign more than 300 years ago? I was originally going to take a picture of this small mirror that amazed the world, but who knew that I accidentally fell into the time tunnel and went back to more than 300 years ago. . . .
