This is an atemoya. It looks like a dinosaur egg/hand grenade hybrid, and tastes like perfume made of gummi bears worn by god.
This is a segment of a pomelo - traditionally eaten during the Mid-Autumn festival due to its resemblance to the moon. Not so good.
The holidays continue for mainland Chinese, who have about a week off for national day and the Mid-Autumn festival. Many, many of them are spending their holiday (and money) in Hong Kong. In this morning's paper there was a photo of a line of people waiting to get into the Louis Vuitton store. Not waiting for it to open, but waiting to get in - there were so many people loading up on ugly handbags that they couldn't all fit in at one time. This is one of the strangest things I've seen in Hong Kong.
