Tang Sanzang should be a coward. He was caught and frightened. But Monkey Sun is not a wild monkey, and the Monkey King has a very high understanding. In the book, it is often mentioned that Wukong talks with Master and occasionally enlightens Tang Sanzang. Moreover, the Monkey King is the embodiment of the spirit of heaven and earth. He studied under Bodhi and worshipped the Great Sage in heaven (though in name only). It is no coincidence that he was born and became immortal and Buddha, and it is closely related to his own ability. Pig Bajie is a pig, but he is not stupid. Although Zhu Bajie has no great skills, he has a good social circle and can laugh with the immortal Buddha. Others may help the Monkey King, but he is a very real person. Friar Sand is a tragic figure, and the road to cultivate immortality is bumpy. After being demoted, he was hurt by Wan Jian, still willingly followed Sanzang to learn Buddhism, and finally joined the Lohan.
