My personal experience on mourning the victims from 5.12 China earthquakes
May 19th, 2008 @ 2:26 pm Hong Kong time. I was walking along streets nearby Central HSBC building. By 2:28 pm all the cars slow down and started all these horn sound, some people along the street stop and lower the head for three minutes to mourn the victims were killed from 5.12 China earthquakes. After that, the street was back to normal.
