Well, I am from China.
The first place I recommend is Beijing. It's a city full of fabulous historical relics and fantastic old building complexes, like the forbidden city, it was the place where the emperor lived. So if you want to experience traditional Chinese culture, then go to Beijing.
The second place I recommend is Wuhan. It is my hometown. maybe people got to know it because of covid. But it's still a city with charm. the charm of food, and the charm of Changjiang, the charm of Wuhan people. Just come here, have a walk at Donghu, and have breakfast in liangdao street, then you will say wow, this is life.
