I'm going to Zibo on April 29th, but I can't book a hotel.

1. Accommodation in different places: If the hotels in the destination are fully booked, you can consider finding accommodation in nearby cities or regions, or choose affordable accommodation methods such as youth hostels and homestays.

2. Adjust the time: If you can't travel just because the hotel is fully booked, you can consider adjusting the travel time and choosing non-holiday or off-season travel, so that it is easier to find suitable accommodation.

3. Seek the help of a travel agency: If the above methods fail to solve the problem, you can consider seeking the help of a travel agency. Travel agencies usually have comprehensive resources and cooperative hotels, which can help solve accommodation problems.
