China science, technology news summary — Dec. 12 –

BEIJING, Dec. 12 (Xinhua) — The following is a summary of published science and technology news of China.
China on Monday launched a Long March-4C rocket, placing a pair of satellites in space.
The rocket blasted off at 4:22 p.m. (Beijing Time) from the Jiuquan Satellite Launch Center in northwest China and sent the satellites Shiyan-20A and Shiyan-20B into preset orbit. They will be used for verification of new technologies such as space environment monitoring.
China’s leading epidemiologist Zhong Nanshan has urged a scale-up in vaccination efforts to inoculate more people with COVID-19 vaccine booster shots, especially with the Spring Festival travel rush coming soon.
“Preparations need to be beefed up. I suggest those planning to travel back home get a booster shot so that, even with COVID-19 infection, they don’t become seriously ill,” he said.
A “digital twin” version of Notre-Dame de Paris has made an appearance on the Bund in Shanghai, part of an augmented reality exhibition that has recently opened to Chinese audiences free of charge.
The historic site Notre-Dame de Paris has been brought to life with the help of augmented reality (AR) and 3D technologies. To experience Notre-Dame in a visual way, viewers are provided with a tablet PC, which they can use to scan a “Time Portal,” similar to a QR code, in front of a cluster of prints, pictures and three-dimensional models in each section.
