 Hong Kong's history has been defined by epidemics, but I don't think we're unique. It's something to do with us as a transport hub of finance, of goods, and of people. And whenever you bring those three things together, you are also allowing the carriage and dissemination of bugs. The Taiping Shan Medical Heritage Trail was established by the Hong Kong Museum of Medical Sciences. It provides visitors a journey through one of the most historic parts of Hong Kong related to health and disease. This area was the most densely populated area in Hong Kong, on Hong Kong Island. We Chinese believe that a human being is composed of two parts, the body and then the soul. So they established what we call the Yi Qi. That means the common ancestral home. So that the tablets of the disease could be placed here. The living condition was very poor at the time. So the government decided to set up a Chinese hospital where Chinese medicine is used to cure the people. So the Dong'er Hospital was found. So there's only so much shopping and eating you can do as a tourist. And I think these trails, especially those with historical significance and contemporary resonance, I think it really helps remind people and they also feel the modern resonance. In Hong Kong, you have this unusual mixture of two peoples with quite different cultural backgrounds who were living rather independently of each other. And when a big crisis comes, this huge cultural difference comes to the forefront. And therefore when the plague came, there were soldiers coming into their homes to look for patients to take away for isolation. They had to remove all the household stuff for disinfection and burning. It was a time when there was a lot of fear, a lot of resentment. The plague became sort of a breaking point regarding the relationship between the colonial government, Dong'er Hospital, local Chinese and the British population. Eventually they decided that Dong'er Hospital should be continued, but they should adopt Western medicine. SARS was really a defining event of modern public health in Hong Kong. Every major jurisdiction that were affected seriously by SARS, mainland China, Hong Kong, Singapore, Canada, all of these places actually either established or substantially beefed up the public health infrastructure, particularly against communicable diseases. So for example in Hong Kong, we established a new Centre for Health Protection. Since we established a trail, we provided regular tools for the general public as well as for special groups like students. If they had the app, it would help them walk the trail and get much more out of it. We hope to have lots of pictures. We would like also to have stories that would bring to life what happened in this area. I think walking through an area allows you really to feel yourself, how it all came to place. We hope it allows people to reflect also when they walk along here on how far we have come as a city and be inspired in some way also. There is always prospects, hopes and aspirations to which all of us should really pay slightly more attention than we have previously been. 2003, we were really not caught very well prepared by SARS. But by 2013, after SARS and after the O9 flu pandemic, I think we're as ready as one could reasonably expect a major city to be.
