远在天边镜在眼前
[yuăn zài tiān biān jìng zài yăn qián]
Far at the edge of the sky but seen right in front of the mirror (meaning someone seems unreachable yet very familiar/close to you in some other aspects or memories.) This expresses the paradoxical situation where a person may feel emotionally distant even when they're physically close, often due to past memories being vividly remembered.
