 People say that when Heaven and earth opened and unfolded, humankind did not yet exist, Nü Kua kneaded yellow earth and fashioned human beings.Though she worked feverishly, she did not have enough strength to finish her task, so she drew her cord in a furrow through the mud and lifted it out to make human beings.That is why rich aristocrats are the human beings made from yellow earth, while ordinary poor commoners are the human beings made from the cord's furrow.
