Art seems like a mystical word, which cannot be easily given one single accurate definition. It has dramatic differences with physics, math, and chemistry, which possess some specific rules and can be described by formulas. But art is not something hovering in the high sky with which can’t be touched. Baudelaire’s poetry, Michelangelo’s sculptures, Picasso’s paintings are, of course, art, while the trees, clouds, and human body we see every day are also art. For me, art is anything that can bring us a sense of beauty. As the saying goes, “beauty is in the eye of the beholder”, and so is art. Anyone can say what is beauty for him or her, and no one can force others to accept his or her own criterion of art. Art is beautiful only when there are no strict rules imposed on it. Our material world is so crowded with countless rules and boundaries that people can’t even have enough room to take a deep breathe and sooth their nerves. The existence of art is to relieve ourselves from daily grind and enable us to enjoy a bit free time.
