Ao Lie and Mo Ang were both characters from the ancient Chinese mythological novel Journey to the West.
Ao Lie, the third prince of the Dragon King of the West Sea, had set fire to the pearl in the temple and violated the heavenly law. After he was saved by Guanyin Bodhisattva, he was enlightened and given the name of White Dragon Horse as a mount for Tang Sanzang. He had performed well on the way to the scriptures. He had defeated demons many times and escorted Tang Sanzang and his disciples.
Mo Ang was the eldest son of the West Sea Dragon King. He was loyal and brave and did not care about personal feelings. After learning that his younger brother, Little White Dragon, had made a mistake, he volunteered to his father and led the West Sea Navy to help Sun Wukong subdue the demons in the Blue Ripple Pond. Later on, he was conferred the title of Namo Black Embellished Spear Heavenly King by Gautama Buddha.
