The correct thing is "summer insects can't talk about ice." It means you can't talk about winter ice with insects that grow in summer. Metaphor is that people are limited by what they see and hear, and their knowledge is short.

A sentence from Zhuangzi's Collection of History, Volume VI, Waipian Qiushui.

The completion is as follows: the well frog can't talk to the sea people, but is limited to emptiness; Summer insects can't talk to ice or time; Qu's family can't talk to Taoists, but can only be tied to religion.

Translation:

You can't talk about the sea with the frog in the well, because its vision is limited by its narrow residence; Insects that live and die in summer can't talk about ice and snow with them, because their vision is limited by seasons; People with little knowledge should not argue with him, because his vision is bound by his education.

Extended data:

Qiu Shui emphasized the complexity of understanding things, that is, the relativity of things themselves and the variability of cognitive processes, and pointed out the difficulty of cognition and accurate judgment. However, this article overemphasizes the uncertain factors of things.

Without revealing the dialectical relationship between relativity and absoluteness in the process of cognition, it is easy to lead to agnosticism, so in the end it can only be adaptive, return to inaction, and of course it is negative.
