Arbutus unedo, strawberry tree.

Seconded. But I’d suggest not eating things until you know what they are. Not all trees bearing fruit are fruit trees.

I agree with floral. Why on earth would you eat something when you don't even know what it is ?

there was no fallen fruits around the tree, and most of the fruits on the tree are green. so i think that birds, insects and human probably already ate all the red ones.

Agreed. And they taste pretty awful anyway. I like this species, especially if allowed to grow into a big tree. Very slow growing though.
