Be sure to do your homework in advance and have a general understanding of the country's history. If you are going to the old city, it is even more necessary to understand its history. Otherwise, it will be a blind tour, and you will not be able to experience the local customs and culture of this place! If you are good at English, you must join a local tour, the explanation is very interesting! I think the food there does not suit the Chinese taste. Jews and Palestinians are actually quite good at mathematics. Be sure to choose a hotel that is convenient for travel, even if it is a little expensive. I stayed in an Airbnb at the time. If I were to choose again, I would definitely stay in a hotel!
