 He was born in Changzhou, Jiangsu in 1960 and graduated from Nanjing University of the Arts in 1987.
 In 1992, he went to the China Central Academy of Fine Arts to pursue advanced studies in printmaking.
 Inspired by his early art experience in Yuan Ming Yuan and learning from traditional Chinese paintings, he returned to Changzhou and soon started to use photography as a way of art representation since 1996.
 His renowned works include "Autumn in the Forbidden City" (1997), "Chinese Landscape" (1998), "After Liang Kai's (Song Dynasty) Masterpiece Sakyamuni Coming Out of Retirement" (1998), "I Dreamt that I was Hung Upside Down to Listen to Huizong Play the Zither with Chairman Mao" (2004) and "Nothing to Hide" (2008), among others.
 Apart from his success in digital photos, he started to photograph black and white Shan shui landscapes as an ongoing experimental project since 2000 to rethink Chinese traditional aesthetics.
 In recent years, he has also explored the various boundaries and possibilities of photography by painting his own photos on silk, as well as video & installation works.

Pictures at an Exhibition (Russian: Картинки с выставки – Воспоминание о Викторе Гартмане , "Kartínki s výstavki – Vospominániye o Víktore Gártmane" , "Pictures from an Exhibition – A Remembrance of Viktor Hartmann"; French: "Tableaux d'une exposition" ) is a suite of ten pieces (plus a recurring, varied Promenade) composed for the piano by Russian composer Modest Mussorgsky in 1874.
The Pictures Generation was both the name of an exhibition at The Metropolitan Museum of Art in New York (April 29 – August 2, 2009); and a means to an end in being the first formal labeling of a group of artists exhibited around their appropriation of images from the consumer and media saturated age in which they grew to maturity, both artistically and in years.
 The term originated in response to the 1977 exhibition "Pictures," curated by Douglas Crimp, which took place in the Fall of 1977 at Artists Space in New York City。 The artists exhibited in the aforementioned seminal exhibition included；Troy Brauntuch, Jack Goldstein, Sherrie Levine, Robert Longo and Philip Smith.
John Serry (born 1954, John Serry Jr., in New York City) is a jazz pianist and composer, as well as a composer of contemporary classical music works that feature percussion, on which he also doubles.
 His debut solo album was 'Exhibition' (1979 Chrysalis Records), for which he received a Grammy Nomination (Best Instrumental Arrangement) for his composition, 'Sabotage'.
 The players included Carlos Vega drums, Jimmy Johnson bass, Gordon Johnson bass, Bob Sheppard saxophone/woodwinds, Gordon Gottlieb percussion and Barry Finnerty guitar.
 His second album, 'Jazziz' (1980 Chrysalis Records) received four stars in Downbeat Magazine and feature review of the month in Keyboard magazine; it was also the inspiration for the naming, in 1983, of JAZZIZ magazine by publisher Michael Fagien.
 The personnel was the same as that of 'Exhibition', except with Mike Sembello on guitar.
 Serry's 3rd album was 'Enchantress' (1996 Telarc) about which Downbeat Magazine wrote: "He has a strong sense of melody, his touch is confident, his ideas are sensible and his playing is beautifully controlled."
 Of 'Enchantress', Jim Aikin wrote in Keyboard magazine: "What a pleasure to find that he is back, still turning out charts that turn heads by turning corners."
 and Hilary Grey wrote in JazzTimes: "Serry's fleet fingered runs on songs like the jaunty, catchy 'DYT it' are both technically impressive and subtle."
 'Enchantress' was recorded after Serry had been awarded the Grand Prize in the 1995 JAZZIZ magazine 'Keyboards on Fire' pianist/composer competition, judged by Dave Brubeck and Bob James (grand piano awarded by Steinway).
 The musicians were John Riley drums, Gerry Niewood and Ralph Bowen sax and Tom Brigandi bass.
 All of the compositions (and arrangements) for all three albums were by Serry and he was Producer for 'Exhibition' and 'Jazziz'.
An ethnic exogroup is a group of people which does not belong to a particular ethnic group.
 Many cultures have terms referring to all outsiders, but in practice this often becomes narrowed to the largest outsider group.
 In particular, exogroup terms used by minorities in a particular country often become specific to the majority in that country rather than applying to other minorities as well.
 Exogroup terms are sometimes considered to be derogatory, depending on the word and the context and manner in which it is used.
 They may be distinguished from ethnic or religious slurs in that they do not necessarily designate a specific group, and instead target all who do not belong to a specific group.
Modest Petrovich Mussorgsky (Russian: Моде́ст Петро́вич Му́соргский ; ] ; 21 March [O.S. 9 March] 1839 – 28 March [O.S. 16 March] 1881 ) was a Russian composer, one of the group known as "The Five".
 He was an innovator of Russian music in the romantic period.
 He strove to achieve a uniquely Russian musical identity, often in deliberate defiance of the established conventions of Western music.
South Bergish (German: "Südbergische Dialekte ") or Upper Bergish (German: "Oberbergische Dialekte ") is a group of German dialects of the Bergisches Land Region East of the Rhine and approximately south of the Wupper and north of the Sieg.
 These dialects are part of the Ripuarian group and thus are also called East Ripuarian.
 Ripuarian dialects are also spoken west of the Rhine up to the German border, and in some small areas next to the respective borders in Belgium and in the Netherlands.
 Ripuarian Bergish dialects belong to the Middle German group, and thus are varieties of High German, where they belong to the northmost ones.
 In the North, they border to the East Bergish and the West Bergish aka Low Bergish language groups, which are part of the Low Franconian group like Dutch.
The Star Art Exhibition took place on September 27, 1979 when a group of avant-garde and self-taught (not trained in the Academy) Chinese artists staged an unpermitted exhibition on the railings of the China Art Gallery after being denied an official exhibition space.
 The group is called Star Art Group(Xingxing) which used formerly banned western style, from Post-impressionism to Abstract Expressionism to challenge both aesthetic convention and political authority: their exhibition was closed by the police and they post a notice on Democracy Walls.
 In November, Beihai Park Beijing, the group held their first formal exhibition: Star Art Exhibition (Xingxing huazhan), which includes 163 works by 23 nonprofessional artists.
 Star Art exhibition was a milestone in China's contemporary art.

 Vollumer continues to work with wire mesh and shows her work "Composition in Space" at the Museum of Modern Art's 1948 exhibition "Elements of Stage Design."
 In 1950, she was commissioned to create a mural for the lobby of 575 Madison, where Vollmer created a large wall relief that used wire rods and wire mesh to play with light, texture, and transparency.
 Vollumer visits Giacometti for a second time during the summer of 1951.
 During the 1950s she begins to works with clay as well.
 Additionally, in 1954 she begins to teach at the Children's Art Center at the Fieldston School in Riverdale and continued to teach until the mid-sixties.
 In 1960, Vollmer participates in the NYU discussion series "Artists on Art" with her friend Robert Motherwell.

 In 1963, she joins the group American Abstract Artists (AAA) and includes her work in their exhibitions from 1963 on.
 By 1970 Vollmer's art is working with complex geometrical forms and mathematical concepts, particularly spirals and platonic solids.
 Sol LeWitt wrote a short essay on Vollmer's work for "Studio International" titled "Ruth Vollmer: Mathematical Forms."
 Vollmer protests the cancellation of the Hans Haacke at The Solomon R. Guggenheim exhibition by writing a letter to the director, Thomas Messer, in 1971.
 In 1976, she had a large one-person exhibition at the Neuberger Museum of Art.
