During the 1980s, Zhou Guozhen, based on the local consciousness, began to seek, time and time again, a life-evoking power from the “Yellow civilization” by shifting his artistic vision to the Northwest culture so as to evoke his "Archaic Phase" series. Those works, by integrating the “graceful awkwardness” in primary arts, “dynamics” in Han sculpture, “profoundness” in Tang arts and his own emotion, recreated an animal world full of humanity. From the occasional appearance of deformity to the pursuit of deformity, his works began to show all kinds of deformity effect. Such beauty of simplicity and deformity agrees with people's artistic taste of returning to the nature. Works of this period are represented by "The Persian Cat", "Black Monkey" and Golden Toad.
He admires the purposeful simplicity and natural art of our nation and bravely uses saggar clay, urn clay and zisha mud. Therefore, after 1985 he produced free-hand works which feature being simple, bold and having the feeling of mud. That is a big step from folk art to pure art. The works of this period are represented by "Falling Leaves Return to Their Roots", "Bully Temper"," The MANDRILL" and "The Snow Leopard". Therefore, this phase is called the "archaic phase".
