骚年你刀枪不入庅
[sāo nián nĭ dāo qiāng bù rù mo]
The phrase 'Teenager You are invulnerable' in a somewhat colloquial style could be intended as praise or envy towards young people, suggesting their carefree nature, invulnerability to external harm, or being able to remain unaffected no matter what others say about them.
