旅途医生半途病人
[lǚ tú yī shēng bàn tú bìng rén]
'Journey’s Doctor, Halfway Patient' may represent someone experienced, wise, and caring ('the doctor') during travels but has become weak, lost, or needy along the way. It could also imply someone used to be a helper/guide turned into needing assistance oneself, reflecting on life’s uncertainties.
