Text beyond the screen will not automatically wrap? Solve

recently accepted a VUE project and found a strange place: I write a tag on any page, the text inside is very long, until it is beyond the screen, it will not automatically wrap, it has been beyond the screen, and the width of the censorship element is much wider than that of the screen.
try, English letters or numbers will look like this, but not if it is Chinese? Why?
I have even removed all the styles introduced, but there is still such a problem. What"s going on? have you ever encountered such a situation? It"s urgent to solve
