The hound will eventually die on the mountain, and the general will inevitably die before the battle. What do you mean? From what allusions?

Dogs usually die in the hunting ground, and generals inevitably die in the battlefield. Their mission is inseparable from mountains and battlefields. It's normal to die in the post and make it public.

It means that you need to be careful to do something frequently and repeatedly to ensure safety. Things with obvious hidden dangers will eventually lead to devastating accidents because of hidden dangers and negligence.
