挽留淡然未凄凉
[wăn liú dàn rán wèi qī liáng]
Means 'holding back indifferently yet not desolately'. In terms of relationships, it describes someone who can remain calm during departures or changes in relations and doesn’t feel too sad because of loss or separation, indicating a state of indifference as a coping mechanism when faced with loss, avoiding getting entangled emotionally.
