The natural world is so beautiful now that it radiates bright sunshine everywhere, shows off colorful colors everywhere, flies around with pleasant bird calls and insect calls, and drifts around with intoxicating fragrance. This is a green world, a sea of flowers. Spring is lively, fanatical, graceful and young. Spring is everywhere the shadow of people's hard work, people use their hands to sow their firm beliefs and eternal hope, sow true perseverance and selfless love.
