Kongming Lantern, also called Sky Lantern, is said to have been invented by Zhu Gekongming (Zhuge Liang) during the Three Kingdoms period. At that time, Zhu Gekongming was besieged by Sima Yi in Pingyang, unable to send troops out of the city for help. Zhu Gekongming calculated the wind direction, made a floating paper lantern, tied it with the message for help, and then escaped as expected, so later generations called it Kongming Lantern [1]. Another way of saying this is that this lantern looks like a hat worn by Zhu Gekongming, hence its name. Kongming Lantern-It is said that this lantern was invented by Kongming and used for communication between armies in war. Its working principle is that hot air is lighter than cold air, just like a hot air balloon, but this flight mode is simpler and more convenient to operate. The rising height can reach 1000 meters.
