无孔枷锁
[wú kŏng jiā suŏ]
The phrase '无孔枷锁' (wú kǒng jiā suǒ) translates literally as 'lock without a hole,' symbolizing a form of invisible restriction. It represents emotional or mental constraints, which can neither be seen nor unlocked easily. This pseudonym implies that one feels confined or limited in some aspects of life but unable to articulate it, just like how a lock cannot be opened without a keyhole.
