Qihuan City has a museum of the Republic of China that stood on the outskirts of the city. There are many archaeological excavations in the museum, bronzes, stone tools, and even mummies that have not decayed for thousands of years. Some people say that the Flag Ring Museum is haunted, and many tourists dare not visit the Flag Ring Museum after 7 p. M. Later, the Flag Ring Museum also closed after seven o'clock. There is no security guard in this museum, only Aunt Chen who collects tickets.
Question: Is the Flag Ring Museum really haunted?
