Strokes21Frequency#18891DifficultyVery Hard
Cultural note

In Chinese culture, the concept of accumulation is often linked to the value of saving and resource management, seen in practices like the traditional 'saving for a rainy day' philosophy which emphasizes the importance of preparing for future needs.

Memory tip

Imagine a mountain (堆) of treasure (积) that keeps growing as you keep piling more and more gold coins on top of it. The character 堆 has the radical for earth (土), representing a pile, while 积 suggests accumulation, like a treasure trove that grows over time.
