Can the Bazi, Zhouyi, and horoscope be modified or replaced? Or something can be changed

You seem to be asking: Can luck be changed? Answer: When predicting that something will not go well, you can do it with caution or do it in another way. For example, if you predict that you are going to sell your old car and trade it for a new one, will you see if the old car can be sold smoothly? If the hexagram shows that it is not easy to sell, then you can appropriately lower the price, or expand publicity, etc.

The above should be understood by analogy, and this is also one of the solutions.

If you are asking about completely changing your natal chart (horoscope), how is that possible? Because the natal chart comes from a person’s birth date, the birthday cannot be changed
