I threw away the lotus hairpin I made before, but can I still do this task? If I want to pick up the lotus hairpin again, I can't find it.

If the lotus needle triggers the task, if the task in front of you is completed, you can't get the task if you lose it.

In addition, if you can get rid of it, you can get it again.

Get the organ pig, and go to the Tangmen Chamber of Secrets at Level 80 to get fragments or mission trigger props.
