How is XP shared between party members? [duplicate]

When you gain XP in Genshin Impact, is the XP shared between party members, or is it only the 'active' party member that gets the benefit?

Does that change if the current party/active party member is max level?

Character XP is given to each member of your party, regardless of participation. Dead party members will still receive Character XP. Characters not in your active party will not receive Character XP. Character XP not from materials is gained from quests, defeating enemies, and claiming Boss rewards. So all shared XP only goes equaly to active party members even if they are max level. If you want to level up a character put them into your party.
