Tourist visa - Hotel reservation

We will be in China for 20 days but we booked for an airbnd accommodation for 4 nights only because we intend to join a tour group that may include accommodation after checking out of airbnb, when we are already in China. Then we are going to find a new accommodation after the tour up to the day when we flight out of China.

Do we need a hotel reservation for our entire stay in China for our tourist L type to be approved?
