In the graduation season of colleges and universities, due to the impact of the new crown pneumonia, many colleges and universities adopt the "cloud graduation" and other methods, which makes the graduates unable to arrive at the school, and personal luggage is also sent by the school. Recently, Harbin Normal University used a ladder to help graduates transport luggage. It only takes 30 seconds to transport luggage from the 6th floor to the first floor. Earlier, Harbin Normal University also used "cloth slides" and other methods to help graduates send luggage. (Fan Yingjie Field)
