Where is the space walk exhibition in Nanjing held? How much is a ticket?

China's first spacewalk exhibition will be held in Nanjing Science and Technology Museum on April 25th. The exhibition specially invites Zhai Zhigang, the space hero of Shenzhou VII, to give a popular science report to the public and will interact with children in a primary school. Nearly 100 precious items accompanying astronauts to visit the exhibition will be escorted to Nanjing by the General Armament Department, and only one pair of gloves will be insured for tens of millions of yuan. In the outdoor square of the Science and Technology Museum, there will also be a large space model, including the "Long March II" bundled launch vehicle nearly 30 meters high and the "Shenzhou VII" spacecraft on display in real scale. A new film, Walking on the Moon, was also introduced in the ballroom. During the exhibition, the existing ticket prices of Nanjing Science and Technology Museum will be maintained, including adult 40 yuan, student 20 yuan and parent-child package (two adults and one student) 60 yuan.
