This sign takes its name from an ancient Chinese saying: 'The human heart is never satisfied' (人心不足蛇吞象 - literally 'an unsatisfied heart is like a snake trying to swallow an elephant'). The proverb comes from a folk tale about a greedy farmer who saved a magical snake. In gratitude, the snake offered to grant him wishes.
The farmer asked for gold, then more gold, then a mansion, then power. Each gift only made him want more. Finally, he demanded to become emperor.
The snake, disgusted by his endless greed, devoured him instead. The story became a cornerstone of Chinese philosophy about contentment. During the Song Dynasty, scholars often quoted this tale when advising emperors against excessive expansion or citizens against chasing status.
It's not about having no ambition — it's about recognizing when enough is enough.
