The traditional method of dividing age groups in China;

The United Nations World Health Organization put forward a new age division:

Young people under 44 years old, middle-aged people aged 45-59 years old, young people and elderly people aged 60-74 years old, elderly people aged 75-89 years old, and longevity people over 90 years old.

The division of these five age groups delays people's aging period by 10 years, which will have a positive impact on people's mental health and anti-aging will.

Before 1994, the internationally recognized age groups were divided into children before 14, young adults from 15 to 64 (China is 60 years old) and gradually entering the working age group; The elderly are over 64 years old.
