After getting the Schengen visa, can I change the hotel or itinerary?

Why is Schengen so strict? It’s because Chinese people don’t care about credibility too much. Our seniors have guaranteed that they will definitely return to China within the time limit, but there are also many people who are illegally living abroad. Although the probability of such people is indeed small, the base number is there, which means there are still many people. Therefore, VO must ensure that you are here for tourism and that you will definitely return to your country - you must stay in a hotel to travel, have enough money for your expenses while traveling here, and you can go as a freelancer. And not just for us Chinese, I heard from the French that it is also very difficult to apply for a Chinese visa, and you also need hotel orders, round-trip air tickets, etc.
