三行太长一生太短
[sān xíng tài zhăng yī shēng tài duăn]
'Three Lines Too Long, One Life Too Short' seems to express the complexity of trying to fully convey something meaningful or profound in just a few short lines, emphasizing how hard it is to sum up a lifetime of experience or emotion concisely, reflecting a sentiment that life passes quickly, and there may be much we don't get time to say or do.
