I am about to go on a business trip to Taiyuan. Is there anything I should pay attention to?

It should be a relatively hot season when we come to Taiyuan these two days. Taiyuan is dry and hot in the hot season, and it is quite comfortable in the morning and evening. This is your first business trip, so you may need to bring your ID card when you stay in a hotel. I think staying in a hotel, not near a train station, is very messy. (I think other cities are like this too, haha)
