The Taojinshan Greenway (绿道) in Shenzhen has been open to citizens since July, 2019.Sitting at the west side of Shenzhen Reservoir, it is as long as 7.07 kilometers.

With plants along both sides and lakes lying at different sites, tourists can enjoy wonderful scenery all the way. If they are tired, they are free to take a rest at the 3 stops that were built for breaks. Additionally, five unused guard posts (岗享) along the old route have remained. They serve as sightseeing platforms for visitors to feel the cultural spirit behind the place.

Of all its 13 scenic spots, 8 were designed to have AI helpers. From them, visitors can gain information on parking, tour guide services and more. The smart greenway, with free Wi-Fi available, also provides environmental date, such as temperature, wind speed and air quality. What's more, it can give visitors warnings of coming extreme ( 极端的) weather and natural disasters, including rainstorms and typhoons that may hit Shenzhen.

"Started in the middle of 2015,the building process of the Taojinshan Greenway has taken good care of the wildlife and environment nearby" said Yang Shiming, an official in charge of the project.
