These days the sky looks cloudy owing to dust storm or very tiny grain of sand that is called 'Ko-u-sa' from Chinese continent.
I couldn't see the mountains far away clearly today.
Now is the season of cherry blossoms, so we want see them under the clear blue sky.
But we can't do anything about the phenomenon. 
Taking a walk, I saw this beautiful tree.
Though I don't know the name of this tree, white flowers are in full bloom now.
