The full name of Xiao Lang is Qin Lang. When the welfare institution found him, he was just a child who had learned to speak, and aside from his own name, he could barely articulate anything clearly.
After Leng Yichen adopted Xiao Lang, he officially changed his surname from Qin to Leng. However, the name Leng Lang sounded too severe and didn't resemble a child's name, so Bai Yiran decided to add the character Yan between the two characters.
Hence, Xiao Lang's name officially became Leng Yanlang, and he was enrolled in a kindergarten. After all, Bai Yiran still had to work, and Xiao Lang could not stay at home forever; he needed to make new friends to quickly integrate into the life here.
In the morning, after dropping Xiao Lang off at kindergarten, Bai Yiran went to work as usual.
