During the academic year, Njeri said the children, who hail from different schools, attend training on Saturdays and Sundays from 2-4 pm. However during holidays, they show up for training daily, an indication that they enjoy the activities.

"Attending the training on a daily basis has shield the girls and boys from engaging in peer-pressure activities like sex, drug abuse and crime. By the time they go back home, they are tired and just want to sleep. I'm truly grateful to the Dream Building Service Association for such an initiative," she said.

Chen Hong, a 22-year-old mechanical engineering major who arrived in Kenya four weeks ago, is one of the Chinese volunteers who is at the forefront to give the slum children a new lease of life.

Chen learned about the program in the Mathare slums following a lecture at his institution by the founder of the charity organization.

"I felt obliged to travel to Africa for the first time, and participate in helping youth to hone their art skills, which they can use in the future to earn a living. I'm enthralled by the skills and the confidence that the children are exhibiting," he said.
