一朝悲欢共十年生死同
[yī cháo bēi huān gòng shí nián shēng sĭ tóng]
Roughly translating into 'One-day Sorrows And Joy Shared Through A Decade's Worth Of Life Or Death', this signifies the profound experience that within the span between life and death across many years, people can form close bonds over shared sorrows or joys within moments, expressing the fleeting yet profound depth of human connections.
