The dog days of summer in Nanjing do make people feel the scorching heat of the stove, but the summer rain these days also makes people feel the joy of being hearty. During the day, the sun was shining, the sky was clear, and the sun was scorching. In the evening, it started to rain heavily, with wind and rain, lightning and thunder, which was terrifying. However, it doesn't matter if it rains, it washes away the dirt of nature, the irritability of people's hearts, and the heat of the weather, bringing cleanness, freshness and refreshment. I stood by the window and watched the rain. The rain was falling on the windows, the awning, and the ground. The green mountains and trees not far away can no longer be seen clearly through the window. Open the window and breathe a sigh of relief. Waves of fresh and cool air hit your nostrils and are refreshing.
