1. If you want to mark it in the text, it can only be as follows:
When Chen Ziang sent his friends off for the expedition, he wrote, "Don't let Yan Ran go up, but leave the Han generals with merit" ("Send Off") Wei Da joined the army"). (If there is other text behind it, the annotation cannot be placed at the beginning of the next sentence)
Or to save trouble, express it like this:
When Chen Ziang sent Wei Da to join the army, He wrote: "Don't let Yan Ran go up, but leave the Han generals to do their best."
2. If it must be expressed like this:
Chen Zi'ang wrote when sending his friends off for the expedition: "Don't let them go." Yan Ran, only the Han Dynasty will be successful."
Then you can add a small number after the quotation and indicate the source at the end of the paper.
