The day marks the end of the long Lunar New Year celebrations. Families come together, eat sweet round dumplings called 'tangyuan' (which means 'round-together'), and watch lanterns light up parks and streets. Cities hold giant lantern displays in the shape of dragons, fish, flowers and famous buildings.
Pingxi is a small old town high up in the hills outside Taipei. Hundreds of years ago, people there lit paper lanterns to send a message to family in the next valley - 'we are safe'. Today, the tradition continues but in a much bigger way. Tens of thousands of visitors come during the festival to release their own lanterns.
Each lantern is made of thin paper stretched over a wire frame, with a small candle inside. When the candle is lit, the warm air inside the lantern makes it rise - the same way a hot air balloon works. People write their wishes on the lantern before they let it go. The lanterns drift up, glow against the dark hills, and slowly fade.
Modern Pingxi lanterns are biodegradable - which means they are made of paper and string that breaks down naturally after they land. Local people collect them again after the festival to keep the mountains tidy. Many schools join in by writing class wishes on a shared lantern and releasing it together.
