Misunderstanding (1): The introduction from friends and advertisements suggests that the most favorable approach is to personally visit the manufacturer of the toilet paper rewinder. This visit will facilitate the provision of efficient after-sales service for the machine in the future.

Whenever we rewind something, our main focus is on achieving speed rather than prioritizing quality.
