Strongly recommend a good place to go: Sichuan Science and Technology Museum. Chengdu's city level is no higher than that of Beijing, Shanghai and Hong Kong. Don't expect too much. But as soon as we entered, we were knocked down. It was amazing. The whole venue was divided into three themes "Three Questions, Three Searches and Three Lives" with exhibition areas on the first to third floors, science clubs on the fourth floor and 4D cinemas on the fourth floor. The two spaces between the buildings are used as "Children's Natural Ecology Paradise" and "Dujiangyan 1:80 Miniature Model" respectively. All kinds of facilities are well maintained, with high utilization rate, many interactive activities and very good experience. We played for five hours without stopping, and we never stopped. Please book free tickets online one week in advance for summer vacation. It's open at 0:00, and it's sure to be full by noon. It's too hot.
