 Okay, all right, colleagues. I'm sorry that it's been kicking me out and in and out for a few times. Anyway, it's an honor to be invited to give a speech over here on healthy cities. And since the whole meeting is about forestry and I also have my colleague actually dream young help to include a couple of slides in here. So first a brief history of healthy cities, the initiatives in China. It started in, you know, the world started in 1984 in Canada, but in China started in 1989 for a few pilot areas. And then 94, you know, always through for some important cities during this period actually some colleagues from Australia, United States and also Europe have joined us to help the development of healthy cities in China through collaboration with the Health Commission of China. And you can see from this diagram it's about 2016 that President she has elevated the country to build healthy cities and healthy townships. And in 2018, there's a national healthy city indicator system issue. And during about that time between 2016 and 2018, I was asked, invited by Lancet to develop a commission paper on healthy cities in China. So essentially we named that commission at Qinghua Lancet Commission on healthy cities in China. So we have some we identified a few major achievements, including China's healthy. Not healthy. It's There are some national patriotic health movement. And then there are some key efforts we realize that are needed to basically in that report we find five areas that need to be enhanced in order to improve urban health and to address urban health challenges. So, hopefully, we were promoting that China could develop a healthy cities movement on top of in the 1950s, 60s targeting healthy environment. So as you can see that as the pilot study and also some subsequent efforts in China, healthy city movement and development in China has indeed increased the city's preparedness to combat even COVID-19. So we have in this particular diagram shows that while the pilot cities are actually able to diagnose cases more and earlier than the other cities that have not developed the healthy city efforts. And there are also, you know, many actions in we did a calculation on various kind of aspects for building healthy cities in China. So, more than 100 perfectures level cities have passed healthy city plan. And we basically develop some some evaluation areas, including whether or not they have conducted baseline survey, whether or not the healthy city movement are being led by the mayors or the leaders of the city and capabilities in the public health in terms of R&D investment. So you can see that there are quite some number of perfecture level cities that they are taking action. So there's some progress being made in China. Now there are some new health challenges. Basically, there is an older population issue in China and also major causes of death among urban residents are moving from in the before 1980s, mostly infectious disease, but now they are mostly chronic diseases and cardiovascular diseases are ranked as the highest over the years since the 1990s. So, of course, this is being last year it is additional basically COVID-19 as a new threat into the healthy cities challenges. So starting from 2019, particularly through the help by the State Council, not at the National Health Commission level, it's elevated to the State Council to propose the action plan for healthy city, healthy China in 2019 to 2030. We are interrupted somehow by the COVID-19, but overall the country is in action toward accomplishing more than 125 indicators or aspects for healthy China development. And how do we align healthy cities with healthy China is actually an interesting research area. Another thing is like what I mentioned that we do hope and indeed lots of research are suggesting that there are great health co-benefit from green developments in China. Basically, green development in cities are having a number of functions that benefit human health. So these are the different areas which I will not read one by one for the sake of time. So basically these are my slides to share with colleagues for this panel. Thank you.
