When determining that the first information includes information about a to-be-processed transaction of a target event, the first electronic device generates a first smart scene service of the target event based on the information about the to-be-processed transaction, where the first smart scene service provides the first user with a reminder service and/or a planning service of the to-be-processed transaction. The first electronic device sends a part or all of the information about the to-be-processed transaction to a second electronic device of a second user. This can implement information sharing of a smart scene service between a plurality of devices.
