共沐清喜森浓不绿
[gòng mù qīng xĭ sēn nóng bù lǜ]
The original expression may not make complete literal sense but might express 'sharing pure joy while staying true to one’s self.' It seems to indicate a shared experience of happiness in nature without losing oneself to superficial pleasures. Or it may imply people who together appreciate simplicity and the beauty that doesn't seek change through color green.
