As a master of 20th-century art and the pioneer of Cubism, the name of Picasso, who passed away in 1973, has long become synonymous with modern art. Interestingly, however, his name was once also a byword for eccentricity and mischief in everyday language. Spanish poet Rafael once said, "Picasso astonished the world; he turned it upside down and gave it new eyes." 　　This animated film uses Picasso's process of drawing a bull as an example to illustrate the creative thinking of this artistic master, which differed greatly from that of ordinary people: what others considered the endpoint, he often treated as the starting point. Once, while drawing a bull, his first version was highly realistic, with rigorous and lifelike structure. Yet, unsatisfied, he proceeded to create ten more versions. The lines gradually became more simplified, and the form of the bull increasingly abstract. By the final version, only a few sparse lines remained, to the extent that viewers could hardly imagine the effort the artist had invested when they saw the finished work. Yet those simple lines masterfully captured both the form and spirit of the bull.
