清烟无瘾
[qīng yān wú yĭn]
'Qingyan Wu Yin' literally means 'clean smoke with no addiction'. It metaphorically expresses someone enjoying something harmless, even pleasant, that is akin to smoking but without its drawbacks. The owner might be emphasizing their desire for light pleasures without being ensnared, or expressing their longing for temporary distractions while still staying in control.
