Adults Achieve Oneself, Become Oneself and Others

Old A has followed his master all over the world since he can remember, and he taught him all his skills. The master only told him that they were from the East. Until one time, there was no news from the master after he returned to the mainland. He only left a letter, telling himself that if he didn't come back, he was dead. He told himself not to look for him. If he was tired of his current life, he would go back to the mainland. Old A returned to the mainland, searching for his master and his own life experience.
