Many children in big cities spend all time watching TV and playing computer games. “Survival Holidays” gives them an important change.Is “Survival Holidays” a wonderful idea? Maybe it is.

Even small danger like getting their feet wet or falling down seems very terrible to them.Many people think the survival activities are good for children. Even years later, they will still remember what they have learned. Some have learned to stay calm in different times. Some have learned how to keep safe. Others have learned how to work in a team.
