"Walking on thin ice, like approaching an abyss" is an idiom left by China's famous historical and cultural classic The Book of Songs. The original intention is that people are alive, just like walking on shallow ice every day, with unfathomable ravines next to them. Be careful again. Otherwise, you will step over the ice, fall into a deep river, or fall into a deep ditch and be smashed to pieces. This is a philosophical statement.
