Innovation could provide a brighter future for Taiwan's sky lanterns

The ancient tradition is coming under fire from critics who complain of environmental damage and fire risks. Yuan Quan and Jia Zhao report for Xinhua.

The Chinese custom of flying lanterns goes back centuries. However, while the lanterns are symbols of peace and good fortune, they are now under threat.

Traditional sky lanterns are made from paper wrapped round a bamboo frame. After rising 300 to 500 meters in the air, the flame suspended from the base goes out and the lantern falls to the ground.
