Are there many cases where hotels can't be booked in the national examination?

A lot. There are many candidates for the national examination, and hotel resources are limited, so many candidates can't book hotels. The national examination refers to the civil service examination of the central and state organs. It is a way for national ministries, departments and general administration to recruit staff in central and state organs. The recruitment conditions are relatively strict. Generally, full-time undergraduate graduates and previous graduates are required, and some positions require graduate students, with CET-4 and CET-2. The time is relatively fixed, focusing on 10- 1 1 every year.
