I have to. According to official website of Shenzhen Science Museum, visitors need to visit on time according to their scheduled time. If they miss the scheduled time, they need to refund the ticket and buy the scheduled time again. Therefore, Shenzhen Science Museum has to go in from 10 to 2: 00, and if it can't get in, it needs to be refunded again. Shenzhen Science Museum was built at 1987, located at the intersection of Shangbu Middle Road and Shennan Middle Road in Futian District, Shenzhen, with a construction area of 12000 square meters, a permanent science exhibition hall and an activity area of 5000 square meters. It is one of the "eight cultural facilities" invested and built by Shenzhen municipal government in the 20th century, and it is also one of the earliest popular science venues built in China.
