Los insectos de verano no recuerdan el invierno

Missing, extremely new, or very obvious to obtain.

The Chinese title (夏虫不可忆冰, which roughly translates to "summer insects cannot remember ice") is a phrase that comes from the Zhuangzi Jishi. It means that an insect can't comprehend or experience what ice or snow is, considering their life cycle only spans summer months. It's a metaphor to illustrate how time can limit one's understanding and is also a comparison for those with shallow knowledge who fail to grasp greater truths.
