"Characteristics of Hot Air" Water Cycle in Nature PPT Courseware 2

Kongming lanterns are said to have been invented by Zhuge Liang during the Three Kingdoms period. It is said that Zhuge Liang was besieged by Sima Yi and the whole army was helpless. Zhuge Liang came up with a clever plan. He ordered people to bring thousands of pieces of white paper and paste them into countless paper lanterns. A ball of rosin was burned under the lamp, and the lamp floated up. Hanging in the air, the soldiers in the camp shouted: "Mr. Zhuge is sitting on a sky lantern to break out of the encirclement!" Sima Yi actually believed it and led his troops to chase in the direction of the sky lantern, and Zhuge Liang was able to break out of the encirclement. This plan saved Mr. Zhuge Liang's life. Another theory is that Zhuge Liang ordered people to light sky lanterns after every battle to pay homage to the fallen soldiers of the three armies. While expressing his grief, he also illuminated the way to heaven for the fallen soldiers of the three armies. Nowadays, people use Kongming lanterns to pray for good fortune and make wishes, so they are also called blessing lanterns, wishing lanterns and sky lanterns.
