What do people do on tsukimi?

Tsukimi, which means moon-gazing, is a custom to appreciate the mid-September full moon, called chushu no meigetsu.
Introduced from China, the custom spread through Japan in the Heian period (794-1185).
Dango, a kind of dumpling, together with crops from the fields, are offered to the moon and among Japanese pampas grass decorations, people sit and appreciate the beauty of the moon.
In some regions people are allowed to steal the offerings.
