(ECNS) -- Thirty-five models of architectures recording the history of the Communist Party of China (CPC) were on display in Changsha University of Science and Technology.
One hundred and fourty-two teachers and students spent one and a half months on these models with the help of 3D printing and digital modeling and fabrication.
They drew digital models on computer after on-site survey, restored every part of these models and then pieced them together.
They also designed QR codes for these models so that visitors can learn about the stories behind these architectures by scanning QR codes.
