Give me the most comprehensive 12 constellation features in history

Features of the capricorn:

Capricorn is a symbol of the beginning of winter. In winter, we dedicate our absolute consciousness to those who were born in Capricorn without reservation. Capricorn people, especially when there are several planets in your constellation at the same time, you will be a realistic and ambitious person; at the same time, you will be easily conquered by enthusiastic feelings, A person with a strong spirit of self-forgetting. Your expression is calm and indifferent, not very close, and you like to be alone. You are afraid that others' meaningless conversations will take up valuable time, you are serious, thoughtful, consistent, loyal, reliable, honest, and dedicated. In addition, you are rock-solid, do not compromise, do not tolerate, never report any fantasies. You love to keep yourself in the ivory tower, which is much better for you than to experience the baptism of passion. Being Cautious may lead you to miss many opportunities, so you will feel disappointed and disappointed. However, you are indeed a conscientious and diligent worker and an outstanding organizer. Just like a mountain climb, the glorious future of the capricorn must be exchanged with unremitting efforts. Your success depends on the spirit of hard work and your ability to work, rather than the gift of luck. You do not like to do nothing and do nothing. Your sense of reality has prompted you to constantly improve your work quality and living environment.

Characteristics of AQUARIUS:

After a person with an absolute Consciousness in his seat, he is a person with a new and strange thought in his mind. You often push forward things without considering specific aspects. You are a pioneering person. Aquarius is a pioneer in thinking ability over instinct. You are not interested in yesterday but tomorrow. You do not want to ride a bicycle. You are infatuated with the beautiful melody of Strausses, rather than those of Mozart. There is a lack of practical ideas. When you immerse yourself in a certain idea, you will get rid of yourself. People are competing to communicate with you because of your innovative spirit and pioneering ideas. You can see the positive ways, idealism, and generosity of things. However, if you lack a realistic attitude, enthusiasm, and are born to never live in peace and have countless hearts in everything, this will eventually make people get bored.

Characteristics of PISCES:

Pisces is the last constellation of the winter and the Zodiac. When it is about to leave in winter, the relative consciousness is left to those in Pisces. This individual has his own unique way of silence. You have a strong interest in everything that happens in the world, and even nothing else. This incomprehensible thought turns you into a mysterious halo, attracting many people. People think that you are quiet, gentle, sincere, and considerate, but they think that your thoughts are so far-reaching and unpredictable. Your desire, passion, and hate are not as full of absolute consciousness as those in some constellations. There is little sense of urgency in mind. You don't understand why you can continue to do things tomorrow. You must finish the work today. Your body is very tired. Noisy, bustling crowd, rush, and pressing pace of life will exhaust you. If there is no more exciting influence on the Mars or Uranus position in your birthdate, then your carelessness will become inertia.

Characteristics of Aries:

Aries is the first constellation of pornography and spring. The life of all things is manifested in the lives of the Aries. The breath of spring gives you new vitality, and you are full of vigor and passion. You need to burn your passionate energy with no regrets. I don't want to make a balance, I don't want to make a perfect decision, and I never pay attention to details. The advantages of Aries are the ability to stand out on the fly, to take action and to make quick decisions. This is a pioneering person. If the time of birth, the sun, or the moon are in this constellation, you will be a vigorous, enthusiastic, Frank, generous, brave, agile, and stubborn person. The downside is that you are not very careful when talking and doing things. You have little room for attention and lack of calm mind and careful thinking.

Characteristics of Taurus:

Following the passionate pastures, Taurus is not a waste of energy. Taurus people do not want to preach without meaning, operate and lose their senses without reason. You don't let your passion go, and you don't have a sense of urgency. This is a person who strongly suppresses the spirit and thoughts and always runs on a certain scale. If there is a strong influence on Taurus in the palace map at the time of birth, you will have a good self-defense instinct. The idea remains unchanged.
