彩虹(Rainbow)

　　hello, i am a piece of rainbow. i have seven colours, theyre red, orange, yellow, green, blue and violet. so im 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 im from the lights dispersion. so im very perfect. now people make some crystal ornament like me and theyre expensive. so im sure they all love me--a piece of rainbow.
