I really can’t go in the summer vacation. There are too many people. I suggest you go to the official WeChat APP of the Science and Technology Museum first. You can buy tickets on the top, so you can save the time of queuing to buy tickets. You can enter the door by swiping your ID card directly. If you two take your children, you can queue up separately, and one person will queue to make an appointment for the project. For example, if you go to the team to buy a movie ticket, it is recommended that the movie buy after 11:00, so that there are fewer people and you can play some small projects. We went on Tuesday. At 11:00, the number of people in the exhibition hall was 17,428 people. ~
