With the arrival of autumn, it became fickle and unpredictable, and the number of patients at the village health clinic suddenly increased, leaving Xia Guifang extremely busy. She had thought that things would get easier after a while, but to her dismay, the number of patients with colds kept rising... Eventually, Xia Guifang herself came down with a cold from exhaustion, and with no other choice, people in the village had to go to the town to seek medical treatment.
