The sky lantern

In ancient China, the sky lanterns were used to transmit messages about wartime or safety, especially people who lived in the mountains, which messages were not easily available. Nowadays, the Feast of Lanterns, one of the three famous festivals in China or Taiwan, people often make the sky lanterns and write their wishes on them, then ignite the tinders on the bottom of the lanters, thus you can see the lanterns fly upward slowly. In this picture, I use long exposure time to make long streams of light.
