    Recently China’s netizens took to the microblogging site Weibo to passionately critique pictures Of the Great Wall in Suizhong County Liaoning province(辽宁省绥中县).

And rightly so.

The New York Times described the flattened section as a “cement (水泥) skateboarding lane dumped (遗弃)in the wilderness .” Let me explain if you haven’t seen in the photos : smooth concrete（混凝土）covers the top, and battlements (城垛) along the edges were completely destroyed--work done in the name of “conservation. " The Great Wall has been a UNESCO World Heritage Site for decades recognizing China's diverse architectural history. Undoubtedly, this particular “conservation” represents a tragedy for the whole world.

As the tourism industry in China picks up, heritage sites are coming under greater public scrutiny(公众监督). Sites that I have visited such as the Summer Palace, Terracotta Warriors and Yu Garden each see millions of tourists every year. As a result, we have grounds to believe that historic sites do need conservation for fear that the inevitable crowds of tourists will trample (践踏) them into dust.

However ，conservation should not only improve physical accessibility it should also retain the character and enhance the experience. One need not look farther than Badaling or Mutianyu in Beijing. While this Great wall restoration provides significant employment opportunities and mostly protects the wall from destruction, it is not without fault. Many visitors complain of overcrowding , the “fakeness” of gauy (花哨的) new architecture and high ticket prices.

Moreover, there is no comprehensive (全面的) academic  publication in any language about the Great Wall. Little scientific knowledge proves the truth of historical and political claims. For instance, UNESCO still claims that the Great wall can be seen from space while China's first taikonaut Yang Liwei stated otherwise.

Unfortunately, the restoration of the Great Wall in Suizhong cannot be changed back to what it was before. Then what can you young people do to support the Great Wall and other historic sites in China? At least it is within your power to learn about the rich history of heritage sites, observe guidelines when visiting them and encourage others to follow your example.
