In traditional China, the family is regarded as the very foundational unit of the nation. In the modem era, the individual takes the place of the family. However, the family is still playing some irreplaceable roles in the fields such as bearing and breeding children, education and giving assistance to family members. Modem China has reformed traditional family ethics of chaxu (order difference) with the application of equality and freedom in accordance of the demand of modem culture. Yet the society has not yet provided enough support to individual families, so that many problems have occurred, which is hindering the development of modem Chinese family culture. In order cope with all the problems, the government should take the leading role in building up a social security system to secure modem family culture, while the society should also take part in the project by all means.
