In Northeast China, "Magpie" is considered as "a thing that loves birds", and magpies will bring happy events to people.
Shao Yong's "Plum Blossom Yi Shu" Guan Dong Ge Xuan: In the early morning, the magpies kept buzzing and travelers came. Huang Xuan Ke Ying Ge: It is said that magpies sing happily, and even when crows crow, disasters do not move. It can be seen that since the Song Dynasty, people have regarded magpies as mascots and omens of happy events.
"Modern Chinese Dictionary": Folklore heard the magpie calling and said that there would be a happy event, so it was called magpie.
