答案：
In recent years many businessmen have been busy selling their goods to the visitors to the Great Wall.
Some people are for this business action. They think since visitors need all kinds of goods, it's right for
some businessmen to sell them goods. At the same time, the business action can offer laid-off workers
work. So the business action is a good thing for the laid-off workers.
But many people are afainsl the business action. As we all know, the Great Wall of China is a
world-famous place of interest with rich historic culture, therefore, it is important for us to keep its natural
beauty. However, the business action reduces the natural beauty and historic sense of the Great Wall.
What's worse, with the development of business on the Creat Wall, a lot of rubbish is produced. As we
can imagine, it will greatly pollute the environment. In my opinion, the beauty of the Great Walllies in the
natural beauty and historic sense, so businessmen shouldn't sell goods on it.
