What should I pay attention to and prepare for my first stay?

Going out is food, clothing, housing and transportation.

Jinan is very cold now. Bring thick clothes and shoes.

It's easy to bring something to eat and drink on the way, but it's expensive to sell at the bus station.

Then take some carry-on luggage, something that is used to being inconvenient to buy.

Then bring your certificate and the right amount of travel expenses.

Besides, it's cloudy recently, so you'd better take an umbrella.
