Every summer month, there is always an old man with a weathered face sitting under a tree or on the roadside, holding a wooden box in his hand and selling songworms. There are many varieties of song insects, and their calls are clear and ethereal but not all the same. It is generally difficult for songbugs to survive past the autumnal equinox, but they can be kept until the Spring Festival if they are properly kept warm. However, there is a kind of chirping insect. According to legend, its cry is like the sound of nature. It hatches at the frost and emerges at the beginning of winter. At the winter solstice, it is packed in a small and exquisite nanmu box and sold. Experienced players will tell you that you cannot buy this kind of bug.
