Jinan is well paid, and the working environment is basically developed by permanent customers (Beijing, etc. ) volunteering to work overtime every day is a bright spot. It's basically at night 1: 30, and I don't rest until around 2 o'clock. It is a good place to exchange health for money. If you are in good health, you can work for several years!
But on a long-term business trip, I generally don't stay in Jinan.
