太阳再亮也会沉落
[tài yáng zài liàng yĕ huì chén luò]
'Tai Yang Zai Liang Ye Hui Chen Luo' can be directly interpreted as 'The sun will still set no matter how brightly it shines'. Its meaning carries the notion of impermanence of good times. No matter how bright things may shine, there always comes a time when light dims. But like sunrise follows sunset everyday, there are still reasons to look forward.
