When Chen Ziang sent his friends to war, he wrote, "Don't let Ran Yan join the army, just leave Gong Hanjiang" ("Send David to join the army"). If there is anything else to follow, the comment part can't be placed at the beginning of the next sentence. )

Or to save trouble, say this:

Chen Ziang wrote in "Send to the Army": "Don't let it go, just keep Han Jiangong."

2, if you have to say:

When sending his friends to the war, he wrote: "Don't let them go, just leave Han to take over."

Then you can add a small number label at the back of the citation and indicate the source at the back of the paper.
