十年戎马心孤单十年老友温如玉
[shí nián róng mă xīn gū dān shí nián lăo yŏu wēn rú yù]
This phrase translates to 'ten years spent in military service left the heart lonely, while ten years’ friend remains warm like jade.' It evokes nostalgia for steadfast friendships that provide warmth and comfort amidst solitude from years spent in hardship or duty.
