We have seen versions of this sky every single day since we arrived except one: the first day. Guangzhou is a port city, nestled into the head of the Pearl River delta. In this way, it is not so different from Philadelphia, the city in which I grew up. It is also a southern city, more like Tampa in its seasons (9 months of summer).
The rain is not ever present, but always at the door, and could come in at any hour, and stay, like an uncle, for 10 minutes or 10 hours. I look forward to some sun.
