On the evening of May 7, flocks of tourists thronged the Cycad Garden of South China Botanical Garden to catch a glimpse of fireflies with their cameras. With the arrival of another Chinese solar term, the Beginning of Summer, the evening in Guangzhou is turning more brisk. As night falls, the tourists get surprised to see a blink of bright light weaving and flying around the grass near Cycad Garden, illuminating the darkness like the Milky Way in the sky. How lovely those fireflies are!
