The ducks raised by the owner of the teahouse liked to lay eggs in the ashes. When he was cleaning out the tea leaves from the ashes, he found them inside. Some duck eggs, after peeling off the shell, are found to be dark and shiny, with white patterns on them. They smell a special fragrance and taste refreshing after tasting.
