|---|---|---|
| Aries | March 21st - April 19th | April 19th - May 13th |

The essence of the controversy in "The 13th Constellation" is the collision of two cognitive systems. Astronomy pursues objective facts, while astrology is essentially a cultural symbol system. As a netizen joked: "When I knew I was an Ophiuchus, my first reaction was to check my fortune - which just proves the power of cultural inertia of the constellation." Perhaps the most important revelation of this discussion is: In an era of prosperous science, humans still need the romantic imagination of mysticism.
