What cities in China are suitable for experiencing the cultural customs?

To experience the cultural customs, I personally think that Tibet, Xinjiang, and Yunnan in China have unique experiences. For example, walking on the streets of Lhasa in summer, walking around the Potala Palace, Jokhang Temple, and Sera Temple, you can feel that you are close to each other. An exotic hometown. Sitting in the Maggie Ami Restaurant on Barkhor Street, tasting a cup of butter tea, eating a Tibetan meal, basking in the sunshine of the plateau, watching the worshipers of faith coming and going, kowtowing and praying. Looking at the snow-capped mountains and glaciers in the distance is the most comfortable travel experience. Every September, you can come to Dali, Yunnan to experience the Bai people’s Torch Festival. From the ancient city of Dali to the March Street Market, you can feel the Bai people’s passion for fire. Worshiping nature, the entire ancient city's torches lit up the sky over Dali, and the ocean of joy lasted until late into the night. Or experience the Water Splashing Festival of the Dai people in Xishuangbanna, Yunnan in the summer. Many tourists gather in the square, bringing water ladles or toy guns, water bags, etc. to play and make noise together.
