紅孩兒
Sudhana is the Buddhist name of Red Boy, also known as Honghai'er (), an antagonist in the classical novel "Journey to the West". Red Boy was the son of Princess Iron Fan and Bull Demon King. As an exchange for punishment after kidnapping Tang Sanzang and Zhu Bajie, as well as irreverently usurping Guanyin's lotus seat, Red Boy surrendered to Guanyin and became her attendant.
