On June 1, 2012, the quiet office on weekdays became very lively, and the sound of children playing was everywhere. This year, EBU ingeniously organized a "happy graffiti event" for the employees' children, and a total of 11 babies participated. The organizer turned the wall of the conference room into a graffiti wall for our babies to play freely and draw the blueprint of the future city in their hearts. Every baby is very serious in drawing on the graffiti wall. The event lasted 4 hours. At the end of the event, many babies left their friends reluctantly.
