With Cheng Su and the others around, there's no way to default on medical bills. Qi Taiguo immediately went to pay them, while Cheng Su stayed and talked with Little Yu.
"...For all these years, Taiguo has been supporting our lives. Without him, we women would have died long ago. Our family only has Old Zheng as a son, two sisters below him, and two elderly parents, with no other hopes. I need to take care of the elderly and bring up the young ones, so I can only pick up odd jobs, which don't earn much. The old folks are getting on in years and have many ailments. Sometimes they suffer silently, preferring to find wild herbs and boil them for medicine."
