Can I modify the Joint Orderg settings if I set them incorrectly?

中文 There are the following three situations: 1. Once a group-buying activity is created and is in the unstarted state (the group-buying activity time has not arrived), only the group-buying settings can be edited. 2. When the activity is in progress, only the activity time can be extended, and other settings cannot be edited. Online group formation, simulated group formation, and over - quota group formation can be set. 3. Under special circumstances, you can perform the [Stop Group - Buying] operation on the group - buying activity that is in progress or has not started. Users who have completed group - buying will not be affected. If simulated group formation is not enabled for users in the process of group - buying, the system will automatically refund the users. If simulated group formation is enabled, the group will be formed directly.
