1. A round coin has a square hole in the middle for Chinese in the past to tie them together.（铜板是内方外圆的。）
2. However, looking deeper, the structure of a coin actually has a life theory to share.（深层面看，其实铜板告诉我们一个人生哲学。）
3. The square in the centre should represent a human mind, facing changes without changing its original shape.（内方，象征着心以不变应万变。所以，人心永远都回保持着自己所坚持的原则。）
4. The exterior circle represents our body, to change itself continuously to suit an unchanged surrounding.（外圆，象征自己以万变应不变。所以，人应该随机应变、入乡随俗，和谁都能在一起，但不会被影响而被改变性格。）
5. Henceforth, the string, which represents almost your public relationship, can go through without any difficulties.（红线，象征着人际关系。人若能像铜板，那与谁相处，都会通畅无阻。）
