"Remember to apply the medicine on time." Lina half-kneeled and placed her hand on an old lady's forehead. The pain that once clouded the lady's face had faded, replaced by a relaxed expression that hadn't surfaced in a long time. The old lady held onto Lina's hand firmly, unwilling to let go. Lina tenderly stroked the lady's hair, comforting her like a child, "Rest assured, you'll be fine. When you get home, have your children change the medicine for you as I have instructed. After a few days, you'll be completely healed. Don't worry; the discomfort will be gone soon. Look, others are waiting for me to heal them, surely you can't bear to see them suffering either, am I right?"
The old woman grinned as she let go of Lina's hand, allowing her to stand up smoothly. The patient's family encircled Lina with grateful looks. Their scarce vocabulary failed to express their feelings; they could only constantly thank her.
