Crows and magpies are ugly. Why do people treat them so differently?

Magpie is especially liked by our ancestors because of its name, so that most idioms related to magpies are auspicious and festive. For example, the magpie climbs plums, beaming, and opens the door to see happiness ... In fact, the magpie, as one of the representatives of the Raven family, is as thick and ugly as the crow, but in people's eyes, it has become the sound of nature. In fact, the IQ of Ravens is what deserves their praise. As for those artificial feelings, different people have different opinions.
