心软是病无药可医念旧是患无药可解
[xīn ruăn shì bìng wú yào kĕ yī niàn jiù shì huàn wú yào kĕ jiĕ]
The phrase translates to 'Soft-heartedness is an incurable disease; yearning for the past is an unresolved condition'. It reflects feelings of being too emotional or attached, which can be seen as a weakness one cannot overcome.
