At the entrance of Kowloon Park is a painting of swans on the lake on the stairs. A pair of white swans face each other to form a heart-shaped pattern. There are many gray doves on the stairs, and one of them is very special, it is white. In the world of doves, there are also different species and colors. Just like humans, there are different skin colors and races, lifestyles, and values, but respect and tolerance are needed between people to make the world peaceful. People live harmonious and happy life.
