Depends on different service types and the requirements of merchants. For services that do not require the merchant to prepare resources in advance, or if the cancellation of the order will not cause loss to the merchant, you can cancel at any time; if the merchant has already made preparations and arrangements for your appointment, your cancellation will cause losses to the merchant, so a cancellation fee will apply. In this case, it is recommended that you change the service time instead of canceling the order to avoid loss.
