Are full-time firefighters in Beijing tired?

Beijing government full-time firefighters are tired. Inquiring about Zhihu, I learned that full-time government firefighters and corporate firefighters have the same job. They will go in case of fire, and it is very tiring and dangerous to deal with the fire. Moreover, they are on duty 24 hours a day, ready to go to the police at any time, and the training intensity is quite high. Therefore, full-time firefighters in Beijing government are tired.
