Chinese people are now living happier and longer than before. According to the latest study, the number
of people over 60 years old is 130 million, making up 10 percent of the whole population, and increases at a
rate of 3 percent per year. This marks that China has stepped into the aged society. It is the Chinese tradition
to respect, love, support, and help old people, and the aging problem has received more and more attention
from the society.
China has built the system to protect and serve old people's legal (法律的) rights and interests, gradually
developed social insurance, public health services and social welfare (福利) projects for old people, and also
applied the minimum living standard protection (最低生活保障) system for the aged who are unable to work
and receive no supports. Now, China is bringing the aging problem into the work of sustainable (持续的)
development according to China's conditions, to build and develop a social security system for old people, set
up a system combined with the state, collectives (集体) and families to solve the problem of"the elderly should
be provided for". The life of China's old people is more colorful along with the fast and sound economic
development of the country.
Old people in today's China who don't have to consider their food and clothing hope to live more colorfully.
The happy psychology (心态) of the aged makes them thirsty for knowledge. Strong and healthy old people
can be seen everywhere of the country. They learn new knowledge, surf the Internet, practice handwriting and
drawing, and take part in fashion shows, exercises and entertainments. Their active and sound living attitude
encourages the youth around and they are in fact an important role in ensuring a stable and peaceful society.
