Richard Horton, the Lancet chief editor, called on people to join China in mourning on his Twitter page on Friday and praised the effectiveness of China's actions in the face of the COVID-19 pandemic outbreak.

"China mourns those who died from coronavirus, especially health workers on the frontlines of the pandemic. We should make April 4 a global day of mourning, recognition, and respect," Horton wrote.

China held a national mourning on Saturday for martyrs such as health professionals, cadres and staff members, as well as community workers who sacrificed their lives in the fight against the COVID-19 pandemic and compatriots who died of this.

A moment of silence was observed by the public across the country. Air raid sirens blared. Cars, trains and ships honked horns. In order to express deep condolences to the people of all ethnic groups to those who have died.
