My Favourite Colour

Different people have different favourite colours. My favourite colour is green.

Green is the symbol of life. It reminds me of fresh trees and grass in spring. Last year I felt upset because of bad grades. When I walked in the park, the warm green plants cheered me up at once.

Green brings me positive energy. Whenever I meet difficulties,  it encourages me to keep moving forward. It teaches me to stay hopeful all the time.
