"Magpies fly in the dark at night, and the bridge spans the morning glory to weave stars" comes from Zhao's "Partridge Day Qixi" in the Song Dynasty. It means: people are serving magpies to fly to the sky in the dark, crossing the magpie bridge, passing through the morning glory and the weaver girl.
"Cowherd and weaver girl are shallow, when will the machine stand on the stone?" Crossing the Yellow River on Qixi Festival by Wang Yuanliang in Song Dynasty means: When will the Cowherd and the Weaver Girl cross the Milky Way?
