Sai Tai Sui (賽太歲; literally “Equivalent to Tai Sui”) is a demon king and an antagonist of the classic novel Journey to the West. He's actually the Golden Haired Hou (金毛犼), the steed of the Bodhisattva Guanyin. As a demon king, he's based on Qilin Mountain (麒麟山) in the Kingdom of Zhuzi (朱紫國).

Powers and Abilities
Sai Tui Sui is armed with a Broad Axe (宣花鉞斧), which he used in hand-to-hand combat. He also has a set of three magic bells made by Taishang Laojun, known as the Purple-Gold Bells (紫金鈴), which can conjure fire, smoke and dust storms when rung. This is actually his collar.

Past
During his youth, the king of the Kingdom of Zhuzi (then only a prince) had a hobby of hunting. One day, he accidently killed one of the newly-born children of the Peacock Mahayuri. Later on, Mahayuri said that to pay for this, the prince will suffer a lovesick for three years.

Journey to the West
Years later, when the prince had grown up and became the king of the kingdom, the Golden Haired Hou took advantage of the child who guards him sleeping, escaped to the mortal realm, became the demon king Sai Tui Sui, and kidnapped the Lady of Jinsheng Palace (金聖宮娘娘), one of the king’s favourite concubines, and forced her to marry him. Without the lady, the king got sick for three years. Unknown to Sai Tui Sui, the Immortal Ziyang (紫陽真人) has secretly cast a protective shield on the lady, thus anyone who touches her will feel like being pricked by thorns, therefore for three years Sai Tui Sui was unable to touch her.

When Xuanzang's party arrived at the Kingdom of Zhuzi, Sun Wukong managed to cure the king. Right after that, Sai Tui Sui ordered one of his minions to threaten the kingdom once again, but the minion was defeated by Wukong. Angered, Sai Tui Sui ordered his messenger to tell the king that he's waging a war with the kingdom. Wukong killed the messenger and disguised as him, then met the Lady of Jinsheng Palace and told her the truth. With the help of the lady, Wukong managed to take the three magic bells, but after he accidently causing noise by using it, Sai Tui Sui managed to take them back. Wukong resorted to the lady's help for a second time, disguised as one of the demon king's female servant and used tricks to steal the bells from Sai Tai Sui and replaced them with fake ones. The monkey then uses the bells against the demon, caused the fire to surround Sai Tui Sui. However, when he was having no way to escape death, the Bodhisattva Guanyin arrived to subdue him and took the Golden Haired Hou back to Heaven with her.
