Achieving the appointment: On 30 September 2016, I made an appointment with myself for this travel note. At that time, I said: From 1 October to 30 October, I planned to go to Yan'an. Before departure, I typed these words: Want to see the blue sky and white clouds in northern Shaanxi to make an appointment with Horsehoneycomb, it is necessary to work hard to complete. The travel notes mainly introduce Huangling National Forest Park in Huangling County, Yan'an City. The travel notes mainly show pictures with fewer words, mainly let you feel the beauty of nature, too many words are redundant. The Park was approved as provincial forest park by Shaanxi Forestry Department in September 2005 and invested by Shaanxi Zilaifa Industrial Co., Ltd. in July 2010. In January 2012, it was approved by the State Forestry Administration to be promoted to a national forest park. The park will provide ancillary service facilities on arable land outside the park, covering an area of 80 hectares. The core area is planned as Xuanyuan Health-preserving Valley in the north of Yigu; Feilongling Scenic Area in Yiling; Zi'e Temple Scenic Area in Yisi; and the supporting areas are two towns, Chaota Town and Shuanglong Town. Line Location: From the map of Shaanxi Province, Huangling County is located on the main line of north-south traffic in Shaanxi Province, with developed traffic, smooth railway and highway transportation and dense network. West Yan Railway (Xi'an-Yan'an) runs north and south of the county border, linking Yulin in the north and Xi'an in the south; the first-class highway of West Yan (An) in the territory has already been built and opened to traffic, and its export to the park is only 40 kilometers, especially the Yuhua Palace exit of the forthcoming expressway is only 20 kilometers away from the south entrance of the park; nine main highways such as 210 National Highway pass through the county border.
