Hello, I am a piece of rainbow. I have seven colours, they‘re red, orange, yellow, green, blue and violet. So I‘m beautiful, right?

 

　　One colour of mine can symbolize a thing. For example, red is a symbol of revolution and blue is a symbol of the sky. But you can only see me after a rainy day because I‘m from the lights‘ dispersion. So I‘m very perfect. Now people make some crystal ornament like me and they‘re expensive. So I‘m sure they all love me--a piece of rainbow.
