Song Ye, although the general in charge of Ningxi Camp, did not reside there but in the An Nan Prefecture government, half a day's carriage ride away from Li City, and his only sister, Song Liu, was married to Wei Caizhou, the son of a sworn brother during their past military campaigns, two people who knew each other inside out, also considered childhood sweethearts who had stuck with each other to this day.
The Wei Family was set up in Chang City, two hours' carriage ride from Li City. In Song Liu's own words, she did not wish to suffer the jolting trip to seek medical care in Li City. She knew very well that her condition was due to her deep longing for her son.
However, she could not resist when her brother personally came to fetch her, taking the risk of leaving his military camp. If she did not accept this kindness, it would mean she was ungrateful.
Thus, she followed Song Ye and came here.
