The role of peaches is to restore physical strength. There is no special explanation (Sun Quan's expert skill rescue), and each peach restores a little physical strength.

The timing of peach use: when your physical strength is not full at the stage of playing cards, use it yourself; Whenever a character enters a dying state, it is used on the dying character (Jia Xu's total extinction can break this right).

Of course, peaches can be converted into other cards by military commanders, so I won't say this.
