A global citizen, artist and thinker, Ai Weiwei moves between modes of production and investigation, subject to the direction and outcome of his research, whether into the Chinese earthquake of 2008 (for works such as Straight, 2008-12 and Remembering, 2009) or the worldwide plight of refugees and forced migrants (for Law of the Journey and his feature-length documentary, Human Flow, both 2017). From early iconoclastic positions in regards to authority and history, which included Dropping a Han Dynasty Urn and a series of middle-finger salutes to sites of power, Study of Perspective (both 1995), Ai’s production expanded to encompass architecture, public art and performance. Beyond concerns of form or protest, Ai now measures our existence in relation to economic, political, natural and social forces, uniting craftsmanship with conceptual creativity. Universal symbols of humanity and community, such as bicycles, flowers and trees, as well as the perennial problems of borders and conflicts are given renewed potency though installations, sculptures, films and photographs, while Ai continues to speak out publicly on issues he believes important. He is one of the leading cultural figures of his generation and serves as an example for free expression both in China and internationally.
