Modification requires a separate version of word to modify the control page and the replacement page. In this case, you only need to take out the summary page separately and keep the modification mark as the modified modification control page. The replacement page is the summary page of the revision instructions.
Then you can write your changes in ③. The following figure is an example, and the contents in ④ can also be used for reference.
In addition, if you have any questions, you can contact me by email.
