Our company playground equipment has been more popular, some time ago to open a new kindergarten plan to buy our playground equipment, installation work would be done by us, as these things if not professional people to do something is not done well, and playground equipment are the children to play, so safety is very important. I remember once a customer they order playground our equipment results have not, then we go down, this kind of thing is really rare, because our playground equipment is very good, it is because they wanted. So put those devices are removed.
