释放自己最年少的无可救药
[shì fàng zì jĭ zuì nián shăo de wú kĕ jiù yào]
Literally 'Release your youngest self beyond redemption'. This could imply letting go and accepting a side of oneself from youth characterized by rebellious actions without regard for consequence - perhaps as a nod towards nostalgia or an encouragement toward self-acceptance of past behaviors.
