If I understand correctly of what is going on in the video, then the new China’s bullet trains (launched from Beijing to Shanghai and vice versa) operate at 350 km/h. The new Beijing-Shanghai bullet trains could also reach the speed of 400 km/h. According to the speakers in the video, China first built high-speed rail system in 2004, but after 13 years China’s high-speed rail system is considered to be the longest in the world. According to Wikipedia, annual ridership for China’s high-speed rail is around or over 1.44 billion headcount. Unlike China’s earliest bullet train models, newer ones like Beijing-Shanghai bullet trains that just got launched are totally indigenously built and patented.
