What are art galleries?

In any search engine, it is easy to find specific and clear definitions about what art galleries are, however, this establishment cannot be satisfied with artists.  This is our motivation, we did the performance near the Tate Britain. We wrote sentences about what art galleries are in English and Chinese on a car. These definitions are all from the search engines. We sought to question the judgments of mainstream culture to art galleries. This temporary ‘artwork’ was driven through London, finishing with wash off at Deptford Hand Carwash.  A symbolic removal of theses constraints. There is a documentation of our group and it includes the motivation that I mentioned on above.
