The mountain road near the top of the mountain passes through a pine forest, with a high content of negative oxygen ions and a natural oxygen bar. The Wanghai Pavilion on the top of the mountain overlooks the Beidaihe Scenic Area, where Chairman Mao once watched the sunrise. The villa area at the foot of the mountain is not open, so you can't see the "Linyi Building" and "Zhang Xueliang General Building". I have been to Lianfeng Mountain and found that Beidaihe Scenic Area is a mountainous area close to the sea. I went to the Nuhai and over the mountains. The 15-22 bus I took was all up and down the mountain, but it was really interesting for the flat north.
