\"There is no such thing as art，only artists\" E.H.Gombrich said at the beginning of \"the story of art\". Indeed， \"art\" is a topic that will never be told. From \"primitive\" to \"classical\" to \"contemporary\"， it moves from \"shelf\" to \"shelf\" and back to \"shelf\"， from \"change life into art\" to \"change art into life\"， and then \"change life into art\". With human beings from \"community survival\" to \"individual existence\" and \"spiral body survival\" sublimation， it always changes， but no matter how it always changes and sublimation， from life， higher than life， life reduction. It is people's imagination and portrayal of life， and the expression and sustenance of people's true feelings.

No wonder Marcel Duchamp said， \"art is too unimportant. Life is so important. To live with obsession is art. It can be without art， but not without life.\" My best artistic work is my life\". Perhaps my prejudice can be without art， but not without life. When life is enjoyable， it is art. Art is not real， it is to show the truth. It is with the imagination of people in life that art comes into being. From generation to generation， generations have been telling tales from generation to generation， and it is impossible if the last generation or the next generation finishes the story. What we can talk about is the story of our generation， the stories that this generation can understand， the stories we are willing to feel.

Popular in today's world of conceptual art， pop art， minimalism art， behavior art， process art， and modern art can be found in the shadow of Marcel Duchamp， his influence on pop art is direct， and even can be said to be the originator of pop art. Marcel Duchamp was born in France. He was a young painter and accomplished in his career. At the age of more than 20， he was a pioneer painter in Paris's painting circles. In 1913， he has a stereo that works down the \"nude\"， caused a sensation in the United States in 1913， the famous \"Armory Show\"， which he was more famous than Picasso in the eyes of the Americans， is regarded as the best European modern painter. However， as his artistic career began to reach its peak， he suddenly declared that he was no longer engaged in artistic creation， and instead went to play chess.

Marcel Duchamp advocates the freedom， and broke all ties in the art world， argues that \"elegant form of art from the spring snow\"， and give it more \"popular literature or art\" the charm， then let art into art. Duchamp on art negation of authority and disrespect， most typically embodied in two works： one is Vinci masterpiece \"Mona Lisa\" painting beard （also known as \"L.H.O.O.Q\"）； the two is in the urinal signed his works as \"spring\". These two works have appeared in 1920， then became art for the non artistic ideas can not be understood and accepted， therefore， Duchamp in the past 40 years has rarely appeared， unknown to the public， only rarely do the following works， chess entertainment. Until after 1958， with the pop art （take a daily worldling when art genre）， Duchamp was \"discovered\"， his anti art thought quickly become the mainstream of contemporary western art， has no authority without the leadership style of the post-modern art opening situation.

\"Bearded Mona Lisa\" also known as \"L.H.O.O.Q\"； L.H.O.O.Q Elle a chaud is a fast read French Au cul homophonic， metaphor images is lascivious and dirty； Duchamp regarded classic works as objects of openly taunting， showing his true character， ignoring the constraints of traditional discrimination； he put anti art to the extreme， successor to the art movement in the new enlightenment. In 1917， Duchamp masterpiece \"Mona Lisa\"， with a pencil on a goatee， and write below \"L - H - O - O - Q\" （pronounced Elleachaudaucul， meaning \"her ass hot\"）. This is a treat \"classic\" attitude was immediately attacked the defenders of the traditional arts. However， Duchamp question was： why can't we look at the work of \"master\" from another angle？ If we keep the work of \"master\" on our heads forever， our individual spirit will always be enslaved by \"noble\". In addition， it is undeniable that Duchamp repainted the \"Mona Lisa\" has a special flavor， which also was the artistic creation of another road， in 80s 70， there are many ways to redraw the artist creation. Therefore， the significance of Duchamp lies in his questioning of the boundaries and nature of art， which leads us to look at the whole art history and art in a new light and angle of view. And his \"finished product\" art also highlighted the importance of ideas in artistic creation.

There Duchamp gave people a comfort： as long as you are willing， you can live， to live， let yourself free from desire， away from the chase， you can bare-handed， no， but you can master yourself， nothing can stop you. You can live a free， live chic， live happy， live life. So we have to go back to Duchamp， and still have to find out what makes him so attractive\".

To explore Duchamp， he must go into his heart. Duchamp is the most important person in the mind， and his life is in the interior， not outside. He is also the art with the break， he saw， that kind of art we have to accept the reality， in the poisoned people. He chose the latter as a social artist （fame， advantage） and spiritual freedom. He was very clear and confident about what he did， and he never needed to explain， explain， or publicize himself. He dared to face the whole situation alone， as if he were in a shipwreck. The results， he has not been around the sink， but in the calm and silence， put the ship into a new channel.
