In our city, there are many tall buildings and heavy traffic. People live in a world of reinforced concrete. With all kinds of pressure and exhaustion from work, life, and study, they long for a breather. The emergence and popularization of sculptures cater to people's desire to get leisurely from elegant art. It is the joy of stopping and looking back that releases people's inner fatigue. Large metal dolphin sculptures, those art creations that are lifeless but full of emotions, have become more and more integrated into people's worlds and become participants of modern life. Together with urban buildings, they create beautiful scenery deep in the soul of the city.
