More and more museums are free admission for us.Why they do this,because it can broaden our views and let us know more about the history,and people are willing to visit a free museum rather than a charged museum.
But just like a coin have two sides,it may brings some disadvantages .For example,too many people are not easy to control,what’s worse,it may damage the cultural relic.
As far as I’m concerns,the museums can charge according to the number of people,if there are too many people,we can charge a higher fee,if there are few people,we can make a free admission to museums.
