The wise and calm investment master Warren Buffett also has a rock 'n' roll heart! According to the US "Time" magazine website's report on the 18th day, in a video that has recently gone viral on the Internet, Buffett appeared with a long wig and a purple printed headscarf, wearing a black leather jacket and a Scottish tartan skirt, modeling after Axl Rose, the lead singer of the extremely popular 1980s rock band "Guns and Roses", which is quite shocking.
