迟来醒悟
[chí lái xĭng wù]
Waking up late, or coming to realize something after a long time delay. It usually describes someone experiencing regret after realizations of past actions and situations. Those people who choose such nicknames might feel that they have missed out because they realized certain aspects of life a bit later in time. In addition, they are aware and wish they’d learned lessons sooner or better prepare against any possible risks in future decisions before similar incidents reoccur.
