As far as hotel reservations are concerned, Ctrip data showed that rooms booked for May Day holiday increased by 43 percent from the same period in 2019 and rooms of some top hotels are all booked.

Lan Xiang, Qunar's data research director, said that hotel reservations have increased during this year's Spring Festival period due to the travel demands after the restraints.

"Although many people visited relatives and travel during the Qingming Festival, many are still choosing to travel during the May Day holiday because of the length of the holiday," Lan said.

According to the vacation rental provider Airbnb, as of April 5, searches for rooms available from April 30 to May 4 at large cities and hot tourist destinations were about 10 times of that in 2020.
