trip to Inner Mongolia

Yes, you can book on the day of departure but it is better to book in advance in case of ticket sold out. Generally, there are about 20 departures of high speed trains between Beijing Qinghe Railway Station and Hohhot East Railway Station.

There is no direct bullet trains from Beijing Airport to Hohhot and you need to depart from Qinghe Station or Beijing North Railway Station.

thanks for the reply.

Am I right that we can also take the high speed train from Beijing North Railway Station too? Any difference if we go to Hohhot Railway Station instead of Hohhot East Railway Station. Which is better?

Yes, you can take trains from Beijing North and to Hohhot Railway Station. The largest difference is Qinghe Station and Hohhot East have more trains and schedules.
