Women are playing an increasing important part in society today. More and more women go to work to earn money instead of keeping the house or looking after the children. Women have entered many fields of society including scientific field. As we know, many women sports teams, such as Chinese Women Volleyball Team, have won the world’s champions. With the changes in their social role, woman’s position in the family has been improved as well. Husbands are not the masters of wives in many places. Husbands and wife are equal now. They join together to overcome difficulties and share happiness. In spite of these changes, the liberation of women has not been completely realized. Also in some places, women are considered being “things” belong to men. They have little chance to find jobs. They don’t get equal pay for equal job. This is a problem must be solved not only by society but also by women themselves.
