Does SF Express deliver goods in rainy days?

It usually rains for about two hours, and the express mail will get wet.

But the courier's delivery on that day is usually finished, even at 8 pm and 10. But when it rains lightly, the courier is not afraid. They also have rain gear that will cover express mail. If it rains, it needs to be sent. But if it rains heavily, we can only wait until the rain stops.
