"Journey to the West" is one of the four classical Chinese classics, telling the story of four Tang monks and apprentices learning scriptures. Among them, Zhu Bajie, Sha Monk, White Dragon Horse and Monkey King represent the pig, rat, dragon and monkey in the 12 zodiac signs respectively. However, among these four apprentices, no characters representing other zodiac signs appeared. Therefore, from the perspective of the zodiac, there are indeed no other zodiac signs in "Journey to the West".
First of all, let's analyze the role of Zhu Bajie in "Journey to the West". Zhu Bajie is one of Tang Seng's apprentices, formerly known as Zhu Wuneng, who was beaten into the mortal world for violating the rules of heaven and reincarnated as a pig demon. He has always played a funny and atmospheric role on the way to learn the scriptures, and there are also many battle scenes. Therefore, Zhu Bajie represents the pig in the zodiac.
Secondly, Sha Seng is also one of Tang Seng's apprentices. His original name was Sha Wujing, and he was once the general of the rolling shutter in the Heavenly Palace. He was demoted to the mortal world because he broke the glass, and was reincarnated as a river demon. Sha Seng has a calm personality and is a doer in the scripture-learning team, responsible for carrying luggage and leading horses. Thus, the sand monk represents the rat in the zodiac.
Again, the white dragon horse is the mount of Tang Seng, formerly known as Little White Dragon, who was the son of the Dragon King. Because of his mistakes, he was demoted to a horse and became Tang Seng's mount. On the way to learn the scriptures, the white dragon horse undertook important transportation tasks and helped Tang Seng and his party to reach their destination quickly. Thus, the white dragon horse represents the dragon in the zodiac.
Finally, Monkey King is one of the main characters in Journey to the West. His original name was Stone Monkey, and he was named "Monkey King" because he learned martial arts. On the way to learn scriptures, Sun Wukong has always been responsible for protecting Tang Seng and solving difficulties. He is smart, witty, brave and invincible, and is the core of the entire learning team. Therefore, the Monkey King represents the monkey in the zodiac.
Through the above analysis, we can see that there are no characters from other zodiac signs in "Journey to the West". The entire scripture learning team only represents the four zodiac signs of pig, rat, dragon and monkey. Therefore, according to the requirements provided and the content analysis of "Journey to the West", there are no other zodiac signs in "Journey to the West".
