<p> In recent years, more and more museums in China have been opened to the public for free. The number of museum exhibitions and visitors have increased significantly. Queuing up in front of some popular museums is very common, and these museums must take measures to restrict the number of visitors. Today, the form of exhibitions is becoming more diverse. Some large museums use advanced technologies such as multimedia and virtual reality to make exhibitions more attractive. Many museums also hold online exhibitions where people can view rare exhibits on the internet. However, the experience of viewing exhibits on site is still more attractive to most visitors.</p>
