Spirit honored

Collaborative Innovation and Self-reliance, a long-term exhibition that is going on at the National Museum of China, pays tribute to heroes of several generations who have committed themselves to China's nuclear and satellite projects. It hails the spirit of "two bombs, one satellite" to encourage people, especially the youth, to make efforts to build the country into a powerhouse of technology. The exhibition, a collaboration with the State Administration of Science, Technology and Industry for National Defense, shows 110 artifacts, models and artworks, as well as more than 500 photos. It traces the industrious course to develop an atomic bomb, a hydrogen bomb, an intercontinental ballistic missile and a satellite. The exhibition shows group images of scientists, technicians, officers, soldiers and construction teams who worked on the relevant projects, as well as individuals such as Deng Jiaxian (1924-86), a nuclear physicist known as "the father of the Chinese nuclear bomb".

Debut exhibition

Xie Qi sources subjects in her paintings from friends, daily objects such as banknotes, plants and candid photos. She employs concealed brush strokes, blurred boundaries and gloomy, hazy tones to convey warm emotions, desires and tension. Summer Heat Has Been Gone for Years shows dozens of oil works Xie has created since 2019 at Galerie Urs Meile's space at the 798 Art Zone in Beijing. The exhibition, running through Oct 24, dwells on Xie's sweeping imagination with which she captures her subjects. Her debut show allows visitors to understand her style of painting, which gives shape to the seemingly empty spirit of humans and the undercurrents of their desires.

Brazilian master

Helio Oiticica (1937-80) had a profound influence on Brazilian avant-garde landscape. HO in Motion, at Lisson Gallery's space in Shanghai until Oct 30, introduces to audiences the master's experimental practices. The works on show trace the complex evolution of his art, as the cosmopolitan traveler moved from Brazil to London and New York before returning to Rio de Janeiro, and his works became infused with a global vision to reflect changing cultural and social contexts. On show are Oiticica's geometric paintings, which burst with the rhythm and spirit of Brazilian culture. An experimental video work, titled Helioframes, made in 1979 in collaboration with Brazilian filmmaker Ivan Cardoso is also on show.
