It was better when the dragon came, thought Vimes. After it'd killed someone it was at least still a dragon. It went somewhere else but you could say: that's a dragon, that is. It couldn't nip over a wall and become just another person. You always knew what you were fighting.
In mine and many other east Asian cultures, the dragon traditionally symbolises things like power, wealth and strength (imperial symbol and all)
I think we often forget that in the story of the Great Race, the dragon came in fifth because it'd stopped to give people rain. Then it'd stopped again to push a rabbit adrift on a log across the wide river so it reached the shore safely (that's why the Rabbit year comes before the Dragon).
Dragons aren't meant to just be powerful - they are meant to do good with such power, and to help those in need.
So in this lunar new year, I hope you gain more power, so that you might be able to help others. I pray you have abundant resources so you may give to yourself and those around you. I wish you courage, endurance, kindness and generosity, for yourself and your people.
I hope you, and I, will be rain givers, life preservers, joy bringers.
I hope we will be dragons.
Extremely belated postscript that should have been here far earlier:
I love the idea of kintsugi so here's a porcelain dragon that highlights the broken seams with gold. Despite all the pains of hardships in life, we are beautiful.
