Sun Wukong
The Monkey King comes to the entrance of a temple of which resides a magical taoist martial artist named Puti Zhushi, who initially refuses to let him in. The Monkey King waits outside the entrance for many months, refusing to leave. Puti Zhushi is impressed with his persistence and allows the Monkey King to enter. Puti Zhushi accepts the Monkey King as a student, teaching him all advanced Taoist practices including the way of Immortality, telling Sun Wukong it was his destiny to know. Puti Zhushi later advises Sun Wukong never to needlessly show off his skills, for to do so may encourage others to ask him to teach them. He counsels that if you do teach them, they may go on to cause trouble, and if you don't teach them, they will resent you for it. He then forbids the Monkey King from ever revealing who taught him, and loyal Sun Wukong promises never to reveal who his Master was. With that Sun Wukong awakes back in the forest, realizing all the years of teaching had taken place in some form of compressed time trance. Later, whenever Sun Wukong is asked about his powers and skills, he gives an honest answer when saying that he learned it all in his dreams.
