In recent years, more and more museums in China have been open to the public free of charge. The number of museum exhibitions and visitors to the museum has seen an obvious increase. It has become very common to see that people stand in long queues in front of some widely popular museums. Therefore, these museums must take measures to restrict the number of visitors. Nowadays, the forms of exhibitions become increasingly diverse. Some large museums use advanced technologies such as multimedia and virtual reality to make their exhibitions more attractive. Quite a few museums also hold online exhibitions where people can enjoy the sight of rare and precious exhibits. However, the experience of viewing the exhibits on site is still more appealing to most visitors.
