不花枉少年
[bù huā wăng shăo nián]
Literally means 'Not to revel in one's youth is to waste it.' This user believes that youthful exuberance should not be suppressed; instead, it ought to be fully expressed. There are opportunities to do exciting things or to live a life of variety while young. A sense of adventure and making the most of time spent in youth can be seen in the meaning.
