Ling Hua held her umbrella, but instead of going to the Cangshu Pavilion first, she went to Doctor Zeng's residence.
Doctor Zeng was not in his room, and together with Shen Ping'an, they were in the medicinal garden. Since winter had arrived, Doctor Zeng had people construct a large wooden canopy over the garden, which was then wrapped layer by layer with cotton. During the day when the sunlight was good, the cotton quilts on the top of the canopy would be uncovered, and in the evening when the sunlight faded, the quilts would be placed back again. This not only kept the garden warm but also allowed the herbs to absorb sufficient sunlight.
