The museum has a child car to rent a child is very convenient. I read the comments before I came, so I am very careful not to let the child touch the glass or other items. After all, the child is two years old. It is inevitable that when he puts it on the ground, he will encounter the glass. There is a female security guard on the second floor. Really stared at us all the way, constantly reminding whose children are optimistic, and they are broken to accompany... I have been holding my son, in fact, I touched the glass, and then we hugged in our arms... I really can't bear it. I finally know the reason for the bad review. Then she may be afraid that my bad review is still the same, and she didn't say a word.
