153 meters, is the commanding height of Beidaihe. In 1919, it became the largest forest park in Beidaihe. There are three peaks covered by pine forests in the park. Mainly visit Donglianfeng Mountain. As a local, I rarely visit here. Especially in the summer, there are too many tourists in Beidaihe, and it is really inconvenient to travel. In addition to accompanying guests, I rarely go to Daihe. It is quite comfortable to go to the mountain in winter.
