Chinese legends have it that Goddess Nuwa created human beings by molding clay into human figures. In fact, Chinese ancestors began to make potteries of human figures more than 3000 years ago. In the beginning, potteries were produced as substitutes of human sacrificial victims. In the slavery society of ancient China, slaves were very often forced to be buried alive in order to accompany their dead masters in tombs.
