For the first time, Yang Jingxian' s fullength drama with many acts adapted from the folktale of the Tang monk acquiring scriptures was put on the stage. Pilgrimage to the West takes the Sun Wukong as the typical figure with rebellious spirit and mysterious colour, and exposes the deep social crisis of the late Yuan Dynasty in many ways with deliberate digression in writing. While the playwright is eulogizing the fight against the present system of the oppressors, he advocates that people should convert to Buddhism in order to resist the material desires and extricate from a difficult living. On one hand, the author instills the common people the Buddhist theories: "extricating from human desires and passions" and "all physical existence is vanity " by citing the characters' own experiences, on the other hand, satirizes absurdity of asceticism of religion bitterly. Thisdramaadmits the human' sprimitiveloveanddesireswhichderivefromhuman' snature, atthesametime, displays the scholars' potential desires of purchasing the liberation of personality under the influences of increasing townspeople ' s consciousness in the late Yuan Dynasty.
