Due to cultural changes and reforms, Asian adults and children have leisure activities that are different from the past. Most of the activities are confined within a small space. For example, adults like to pass their free times singing in Karaoke, spending time in the pub, watching MTV, playing majong,etc. Similarly, children spend a lot of time watching TV and VCD, playing TV/video games, doing net chatting, talking long time on the phone, etc. While children education is very important, children leisure activities should not be neglected. This is even more critical for pre-school children, as leisure activities are their main daily activities. One of the ways of solving this short coming is to provide them more outdoor leisure activities. By doing outdoor leisure activities, they will get in touch with nature and, hence, be familiar with nature. At the same time, they will obtain natural science knowledge and have a healthy body.
