There was a fun story when I was little on a Mid-Autumn Festival Mid-Autumn Festival
Back in my hometown all the families will set a table infront of the house under the full moon to worship the moon
Normally foods like moon-cakes,fruits and a cup of water make a "Moon worship ceremony set meal."
Families will light up some fireworks as soon as they finished the ceremony(normally 10-15minutes after they set the table)
All the kids from the villiage will run to the family that has just finished the ceremony following the fireworks to drink up the water on the table.
There was a saying that the kid who get to drink the water will no-longer have bed wetting issues.
I used to wet the bed sometimes so I ran my best to drink the water hoping to fix my issue. turned out I drank too much of it and wet the bed that very night :(
