break-word Content wraps to next line, and a word-break occurs when necessary.

word-break:break-all;

功能：强制换行，连长的英文单词也会被折断；

break-all Behaves the same as normal for Asian text, yet allows the line to break arbitrarily for non-Asian text. This value is suited to Asian text that contains some excerpts of non-Asian text.

keep-all Does not allow word breaking for Chinese, Japanese, and Korean. Functions the same way as normal for all non-Asian languages. This value is optimized for text that includes small amounts of Chinese, Japanese, or Korean.
