Free Admission To Museums
Recently, museums in mounting numbers become admission-free to the public both home and abroad. The purpose of this practice is to offer more opportunities for citizens to explore and get easy access to the world of history, culture and knowledge.
Although free admission to museums enjoys distinct advantages, it also brings harmful effects. In the first place, these valuable cultural relics displayed may be damaged or destroyed consciously or unconsciously by the crowds. In the second place, it becomes a huge economic burden for museums to run as usual without any profits from the visitors.
It is my view that free admission to museums is of utmost significance. For one thing, we should appeal to our authorities to legislate strict laws and regulations to protect these museums. For another, we should cultivate the awareness of people that museums are extremely vital to us humans. It is high time that we attached great importance to our motherlands’ splendid and glorious culture of more than five thousand years.
