姑娘百毒不侵为何流泪少年刀枪不入为何痛心
[gū niáng băi dú bù qīn wéi hé liú lèi shăo nián dāo qiāng bù rù wéi hé tòng xīn]
This nickname reflects a poetic and emotional sentiment. It laments that even though the girl is strong ('immunity to all toxins') and the boy tough ('impervious to weapons'), they both still feel deep pain and sadness. It hints at their unyielding resilience and vulnerability, often used to express inner turmoil in a dramatic or melancholic way.
