<P0-S0> Tove Marika Jansson (] ; 9 August 1914 – 27 June 2001) was a Swedish-speaking Finnish novelist, painter, illustrator and comic strip author. <P0-S1>  Brought up by artistic parents, Jansson studied art from 1930 to 1938 in Stockholm, Helsinki and then Paris. <P0-S2>  At the same time, she was writing short stories and articles for publication, as well as creating the graphics for book covers and other purposes. <P0-S3>  Her first solo art exhibition was in 1943. <P0-S4>  She continued to work as an artist for the rest of her life, alongside her writing. <SEP> <P1-S0> 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. <P1-S1>  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. <P1-S2>  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. <P1-S3>  Star Art exhibition was a milestone in China's contemporary art. <SEP> <P2-S0>  Published in 1946, it marks the first appearance of several main characters, like Snufkin and the Snork Maiden. <P2-S1> Comet in Moominland (Swedish: "Kometjakten" / "Mumintrollet på kometjakt" / "Kometen kommer") is the second in Tove Jansson's series of Moomin books. <SEP> <P3-S0> Hong Lei (; born 1960) is one of the leading artists in the era of China's New Photography movement in the 1990s. <P3-S1>  He was born in Changzhou, Jiangsu in 1960 and graduated from Nanjing University of the Arts in 1987. <P3-S2>  In 1992, he went to the China Central Academy of Fine Arts to pursue advanced studies in printmaking. <P3-S3>  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. <P3-S4>  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. <P3-S5>  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. <P3-S6>  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. <P3-S7>  His selected solo and group exhibitions include "Recontres d' Arles: Arles Phototography Festival" (Arles, France, 2003), "Alors, La Chine? <P3-S8> , Chinese Contemporary Art Exhibition" (Pompidou Centre, Paris, 2003), "Seven Worthies" (solo exhibition, Beijing, 2007), "Seasons" (solo exhibition, Beijing, New York, 2008), 2011 Chengdu Biennale, "Mi Lou" (solo exhibition, Beijing, 2012) and "Perfume This is Not" (solo exhibition, Shanghai, 2012). <P3-S9>  Now he lives and works in Changzhou and Shanghai.
