China has already secured 870,000 5G mobile subscribers in just 20 days after the country kicked off commercialization of the superfast mobile technology, the Ministry of Industry and Information Technology said on Thursday.

China had more than 79 million rural teenagers with access to the internet by the end of 2015, according to the China Internet Network Information Center. Many of them are so-called left behind children whose parents are away working in better-paying jobs in big cities.

China has been the world's largest market for vehicles since 2009. It is also the largest market for Volkswagen. In 2019, it sold 4.23 million vehicles in the country, accounting for 38.5 percent of its global deliveries.

China has overtaken the United States as Australia's biggest partner in scientific research, according to a new report, despite attempts by the country's defense and security services to have Australian universities distance themselves from their Chinese partners, most of which are universities.

China has a four-tier color-coded weather warning system for severe weather, with red the most serious, followed by orange, yellow and blue.
