The description of constellation personality is consistent, but it does not rule out the possibility of complete inconsistency. Aquarius's personality is also between Capricorn and Pisces. (Constellation theory was introduced from the west, and people in China generally prefer to read their birthday fortune from the Eight Diagrams of the Book of Changes. )
Besides, I am lucky to be in the same Amanome as you, but a few years older than you. My personality is the same as that described by Pisces, but some are really far from it.
