If there are seven stars in the world, what disaster will people have?

It is unpredictable, nothing more than natural and man-made disasters, but in the traditional folk sense, it seems to represent a good omen.

Five-star Li China in the period of Emperor Wu of Han Dynasty can be used for reference. However, in some Feng Shui books, it is slightly introduced that the main ups and downs have some disadvantages, which I have not found. In a word, they should be good phenomena.
