These are a big thing in Taipei. They follow on from the Lunar New Year and generally seem to mark the end of the new year celebrations. The ones above in Pingshi (平溪區) are paper with a candle providing the heat to set them going. You write your wishes for the year on them then send them up to the skies.
The grander ones are put together by organisations, usually schools and are displayed in central Taipei for a week.
