忘了牵挂忘了约定
[wàng le qiān guà wàng le yuē dìng]
'Forgotten Worry, Forgotten Promise' portrays forgetfulness about anxieties and commitments made before. It might indicate an aspiration for lightness and living without excessive burdensome expectations. But more likely so, there may lie a tinge of sorrow over broken promises which were once considered significant by heart but ended up being easily forgotten as time went on.
