First, the method of inserting symbols.
It is troublesome to mark Pinyin, because the tone symbols are difficult to mark and cannot be directly input through the keyboard, so we use PPT to insert symbols for phonetic notation.
We first input the pinyin and characters of the words, and then delete the letters that are out of tune.
Then move the cursor to the corresponding position, click Insert, symbol, select the appropriate phonetic symbol, and then insert and close it, thus marking the phonetic symbol.
Second, the word copying method
We can mark it in Word and copy it to PPT.
Type Chinese characters in Word, then click Athena Chu button, confirm and finish, and then copy the characters to PPT.
