Nanjing, August 23rd (reported by Zhu Xiaoying) – Recently, multiple locations across China have observed the same UFO phenomenon. On the 23rd, Wang Chao of the Zijin Mountain Astronomical Observatory of the Chinese Academy of Sciences presented his judgment to the reporter: "This is a significant UFO event. The unidentified flying object is a special type of space vehicle, which is hard to explain using human-made aircraft. The altitude of this vehicle is in space, similar to the height of Yang Liwei's spacecraft, and it was flying very slowly."
