Pierre-Auguste Renoir was brought up in a working-class family, which made him optimistic in his later life. In his world, the so-called art is looking for ordinary happiness. However, this younger impressionism style was challenging the times of rigid salon organization. Different from other painters, the theme of Renoir’s art is full of joy and pleasure. Thus his favorite subjects are women and flowers with natural beauty, children with lovely faces, wines with intoxicating charm and party with heart smile.
