Excuse me, how does WPS play the infinite loop of numbers?

In word and wps, the shape is 0. 1 (. ) 2 (.) should be entered. In WPS 2000, the point above the number is called the top mark, which is input by inserting a mathematical formula. Position the cursor where you want to insert the object, click Insert-Mathematical Formula-Top Mark-Single Point, then enter the number "1" in the object box, repeat * as the insertion method, and enter the number "2". In Word 2000, we first enter the number "12" and select it. Click "Format-Chinese Layout-Pinyin Guide" with the mouse to pop up the editing box of Pinyin Guide. It can be seen that the reference texts are 1 and 2. We enter such a point in the box of pinyin text, click OK and click OK. It's a bit troublesome to enter points here, but it's impossible to use points on the keyboard. Chinese punctuation has two uses: 1. Open the soft keyboard of input method, select "punctuation" and press the number key "9"; 2. Before work, insert a "." Cut to the clipboard in the blank position of the document, and press the shortcut key "Ctrl+V" when inputting pinyin to paste.
