Site testing campaign for the Large Optical/infrared Telescope of China: general introduction of the Daocheng site

The Daocheng site is one of the three candidate sites for the Large Optical/infrared Telescope (LOT) of China. It was discovered by Yunnan Observatories during the survey of potential sites for the next-generation large-aperture solar telescopes of China. This paper describes the overview of the site, the observation platform and the monitor instrument. In addition, simple statistical results are presented (from November, 2016 up to December, 2017). Detailed data results can refer to the overview of LOT site testing and data analysis articles, which were published during the same period.
