incident

Ma Shilin(馬士麟), a scholar from Changzhou(常州), once recounted a personal experience:

When he was young, he and his father studied in the northern tower. From their window, they could see the outdoor flower platform of an old man named Wang who sold chrysanthemums. One day, Ma Shilin woke up early, leaning against the window and peering below. The sky was gradually brightening, and he saw Wang ascending the platform to water the flowers.
