This lot means '事在人為'. We should not give up just because we cannot achieve results in a short period of time. Just as Fan Zhongyue devoted himself to study by making a congee bowl, those who persevere and work hard with perseverance and self-control will succeed. Once you set a goal, give it your best effort, do not give up halfway through, and persistently devote yourself to it, and you will surely reap the fruits of your labor.
