The sun is considered to be at its strongest around the time of summer solstice, as the daylight in the northern hemisphere is the longest. The sun, like the Chinese dragon, traditionally represents masculine energy, whereas the moon, like the phoenix, traditionally represents feminine energy. The summer solstice is considered the annual peak of male energy while the winter solstice, the longest night of the year, represents the annual peak of feminine energy. The masculine image of the dragon has thus associated with the Dragon Boat Festival.
