Where is the lady that Lu Da met in the hotel from?

Original text:

Lu Da and others were in high spirits when they heard someone crying next door. Ruda was bored and asked the bartender to explore. When the bartender came back, Luda saw an 18-year-old woman, followed by a son in his fifties and sixties, and came to the front with a string of beats in his hand.

Look at that woman. Although she doesn't look good, she still has some touching colors. She wiped her eyes, stepped forward and said three hooray. Lu Da asked her why she was crying. The woman said,' I'm from Tokyo, and I don't want to move to Nanjing, because I came to Weizhou with my parents and went to my relatives' home. The mother died of illness in the inn, and the son and father are living this life.
