What's the difference between constellation and zodiac?

The difference is that the constellation only divides all mankind into twelve kinds. Sadly, some people want to believe it. In the past 60 years, there have been more than 8 billion different combinations of Chinese characters.

So in the prediction, the constellation is not listed at all. In fact, western divination is not a constellation, but astrology. Astrology and astrology are completely different things.
