月亮是黑夜的焦点太阳是白天的主心
[yuè liàng shì hēi yè de jiāo diăn tài yáng shì bái tiān de zhŭ xīn]
This name draws an analogy between natural phenomena and people’s roles or states of mind, suggesting that while the sun is the focus in daytime, symbolizing busyness or prominence, under moonlight, things tend to quiet down, representing calmness or serenity. Overall it conveys day and night having different yet equally important themes/activities.
