What constellation is the singer Li Jian's wife "Little Shell"? It's better to have specific information ~ thank you

According to Brother Jian, there are photos (teenagers) in an appointment between Lu and Yu, which are very nice. She fell in love with Brother Jian in college, and now she is a doctor in Tsinghua. Brother Jian couldn't understand her book after he finished, hehe.

Brother Jian's hometown ~ walking in the street? Yes? The scout found out? What kind of beauty' Harbin people ~ learn? Sociology? Yes ~ that's all I know ~

What if Brother Jian doesn't tell us? Is that all you know? Actually, I also want to know.
