Several days passed, and at the Chang'an East Market sick house, a profound transformation had occurred.
A layer of lime powder now covered the muddy ground, and the courtyard, previously overrun with weeds, had been thoroughly cleared. Outside the door, a table held a bottle filled with pure wine, used by visitors to cleanse their hands. Occasionally, one could spot a worker donning a cotton mask.
Of course, the most notable change was the condition of the patients in the sick house.
"COUGH, COUGH!"
An elderly patient lay in bed, incredulously looking at the cotton cloth in his hands. Previously, he had suffered from fever, chest pain, and coughing up pus-filled blood, nearly driven to despair by his illness. Now, the cotton cloth showed only a bit of phlegm, with no trace of blood or pus.
