Select the Ignore All option.

If there are not many WPS documents, and the same spelling is repeated repeatedly, we can select the field with the spelling error, right-click on the selected field, and select the Ignore All option. When I looked at the document again, I found that there were no more wavy lines.

Note that WPS ignores case sensitivity and text formatting. If there are too many spelling errors, you can try to click the spell check below the document. After clicking the spell check, the entire WPS document in the editing state will be disabled by default. Check for errors again.
