Let’s talk about the meaning of the proverb “walk tight across the rocks and slowly cross the bridge”. The correct answer must be taken

It means that when walking on the stone, you need to walk fast, one step after the other, but when crossing the bridge, you need to walk slowly.

Building stones are originally natural stones. They will inevitably move when you step on them. It is easier to maintain balance when you walk fast. People should not fight for the way while walking on stone blocks, nor should they stop suddenly. If the person in front suddenly stops, the person behind will have no place to stay and will fall into the water. So it has to be fast.

There is a risk of falling if you walk too fast across the bridge, so walk slowly
