An estimated 10.71 million students will take China's national college entrance exam for 2020, also known as the Gaokao, starting on July 7. This is the largest organized collective activity nationwide since the COVID-19 outbreak, although it has been postponed for one month due to the coronavirus. For this year, there are more than 7,000 examination sites and about 400,000 examination rooms across China, with around 945,000 teaching staff participating in the related work.
