This lot means "Chugoku Gyakuji" (meaning "to say the opposite of what one has been told"). In other words, it indicates to the parties involved that they should not forget the favor they have received and think of the source. We are surrounded by parents, teachers, friends, and others who care about us in some small way. Their words of advice, even if spoken frankly and without reserve, are painful to hear, and their true meaning is that they hope we will not stray from the path, but walk correctly and steadily. We should always be grateful and carefully accept the weight of their words with the intention of eventually repaying them. If we take them lightly, overlook them, or take them for granted, then one day, when the person who cared for us suddenly disappears and leaves us, we will realize their deep feelings for the first time and be left with nothing but regret and longing. Then you will be left with nothing but regret and longing.
