There are three single eyes in the compound eye,
Two pairs of wings, one large and one small,
There are a total of twelve abdominal segments,
The male dragonfly slowly walks towards the darker and smaller female dragonfly,
dragging the female dragonfly to fly for a while,

The female dragonfly put her tail end,

Two dragonflies form a heart-like pattern,
After a stick of incense,
This unique heart-shaped position continues...
