It was raining heavily. Lin Wantang clutched the faded silk handkerchief and walked slowly on the bluestone road. She had just taken medicine from the hospital and was feeling cold all over. She just wanted to return to the Lin family's old house as soon as possible. Suddenly, a bolt of lightning pierced the night sky, followed by deafening thunder. Lin Wantang was so frightened that he staggered. The medicine bag in his arms was scattered on the ground, and several herbs were swept away by the strong wind and disappeared in the rain.
