Prof. Li pointed out that compared with previous generations, today, which is based on high-speed information interconnection, people spend less and less time on outdoor activities in daily life. People come to realize that well-designed environment will help enhance people’s initiative and the convenience to take part in outdoor activities in daily life, especially the time before and after work.

By analyzing the relationship between the features of communities and BMI, Prof. Li pointed out that vibrant communities can encourage residents to take part in outdoor activities which helps protect residents' physical and mental health. Also, the security of the communities can be guaranteed. Prof. Li believed that creative community designs with rational use of the natural environment help cultivate vibrant communities culture effectively.
