The girl dragon maiden next to Guanyin is the daughter of Sagara-nagaraja, the Dragon King of the 19th Heaven among the "20 Heavens". Shan Cai was one of the five hundred children of the Elder in the Blessed City where Manjushri Bodhisattva once lived.

When the child Shan Cai was born, many treasures naturally appeared in his family and he was named Shan Cai. At that time, Manjushri Bodhisattva was living in Blessed City, so Shan Cai asked Manjushri Bodhisattva to learn the Dharma, and Manjushri Bodhisattva said, "Go to Monk Kung De," and Monk Kung De told him to go to Monk Shan Zu.

From then on, he went to 53 masters, Bodhisattvas, Boromantis, and Immortals, and after a lot of hard work, he finally met the Bodhisattva Pratyekabuddha, and finally attained the "Great Light of the Undifferentiated" and attained the Buddhadharma.
