Yanhao Deng of Chenzhou, Hunan, China, recited 10 country names in Mandarin from memory, 中国、韩国、日本、朝鲜、美国、法国、埃及、印度、智利、巴西 (China, South Korea, Japan, North Korea, the United States, France, Egypt, India, Chile and Brazil), in 2.51 seconds. With eyes shut and a smartwatch stopwatch at chest height, Yanhao starts the watch from 00:00.00, rattles off all ten and stops it at 00:02.51, a lap of five continents at about a quarter of a second per country. RecordSetter checked the clip frame by frame against the watch and the soundtrack: the upload is a screen recording whose sound trails the picture by about half a second, and the spoken list itself lasts about 2.44 seconds, inside the time on the watch.
