In Journey to the West, there is a story about Tang Monk, Elder Tang, traveling with a servant named Monk Sha and two pets, a monkey and a pig. ——Guo Degang

The ears and eyes are wide while the sky and the earth are narrow. If there is little right and wrong, the sun and the moon will be long. The cock crows all night long, evoking the bright moon in front of the window. When I wake up from sleep, I see through the dream. ——Guo Degang
