From 25past9 till now 25past11, it has been raining 2hours.
It make a lot of roofs of the old buildings receiving too much rain drops, & collecting a lot of them, then being full of them, and overflowing from the sky to the ground（maybe the drain outlet had been blocked, or too small to flow too much suddenly rushing water）. A beautiful picture is showing before us, that is: it seems that a lot of rain dragon are opening their big mouth & throwing droplets of rain through the air, with the wind, raindrops are sprayed to different areas.
Quite beautiful!
(At last, it rained 4hours till half past 1pm)
