徳川光圀
In 1656, he attempted to sail back to China, but without success– once again ending up in Japan. This time he received letters from Andō Seian who wanted to become his disciple. Through Ando's help he got special permission to live in Nagasaki in 1659. At first, life was hard as he had little money, but in 1664, Zhu received an invitation from Tokugawa Mitsukuni, grandson of Ieyasu and daimyō of Mito to go to Edo as a senior lecturer in the Toku School.
