龙眼 lóng yǎn

This fruit is called 龙眼 lóng yǎn, literally, Dragon Eye.

They are usually available from June to October

in most areas of China and some nearby countries.

I had fond memories of harvesting and eating these Dragon Eyes in my grandmother's yards when I was little. Her trees were even taller than the ones shown in the pictures. My siblings and I had fun holding a blanket under the tree when my grandmother tried to cut the fruits down with a curved knife tied to a long bamboo pole.
