According to the Wuzhen Scenic Area’s official website and various travel sources, during National Labor Day week (which includes May 1st), most attractions within the scenic area will be closed. The specific operating hours may vary depending on the venue or weather conditions, but generally, there won’t be many activities or services available on that day.
Please note that some major events or festivals might take place around this time and cause changes to the usual schedule, so it’s always best to double-check with local authorities, venues, or your accommodation provider for more up-to-date information.
