Yesterday I saw a beautiful rainbow hang on the sky in the east and it consists of seven colours , red, orange , yellow, green , blue,indigo , violet . I was wondering why it is arched. Maybe the painter made it with a compass. Moreover, everyone likes it as it represents beauty, peace and happiness. There’s a saying we can see a rainbow after raining . The extension meaning is if someone suffer from the tough days he or she will eventually overcome it and make a good result. I hope this rainbow could bring us good luck and end the epidemic soon.
