In Hong Kong, most 'health projects' only focus on individual's physical health and usually separate physical from mental or psychosocial health. This new project focuses not only on individuals' health but on the whole family and holistic health. The investigators strive to help family members influence each other to have better holistic health. The focus on family is a new and unique concept which is an innovative, long-term and highly sustainable approach at the community level. With the involvement of family members, Hong Kong families can develop and change their lifestyles which impact on families' health. The investigators will use a family-focused approach and adopt a holistic perspective to design a sustainable family holistic health intervention model in the community to meet the global health challenges identified by UN.
