In order to celebrate the National Day, a certain unit plans to place flowers on both sides of a 60-meter-long corridor. It was originally planned to place a pot every 4 meters. After the arrangement, it was found that there were some flowers left, so it was changed to a pot every 3 meters. Please help Think about it, how many potted plants do not need to be moved?
