What does the Seven Immortals Congress mean?

The Seven Immortals Congress means that seven immortals meet together. This statement comes from folklore, the story of the seven fairies. In this legend, the seven fairies met and fell in love with Yong Dong. When the Jade Emperor learned about this, he sent a heavenly soldier to take her back because the seven immortals had moved away, but the seven immortals didn't want to leave Yong Dong, so the Jade Emperor arranged a meeting of the Seven Immortals for them. At the meeting, the seven fairies and six sisters reunited with Yong Dong to discuss how to help the poor. Later, people handed down the story of the Seven Immortals Congress and regarded it as a symbol of praying for happiness, reunion and happiness.
