What are the characteristics of the four famous ancient buildings?

The four ancient buildings are: stork tower, yellow crane tower, Yueyang tower and Wangtengting. Yueyang Tower is located in Yueyang City, Hunan Province. It was originally built for the needs of war. Soldiers are practicing on the field, and the leader can't see the state of no one. So he built this building to facilitate the observation of soldiers' training, and it has never been demolished. Up to now, Yueyang Tower is also the best preserved building among the four Gu Lou. The Yueyang Tower written by Fan Zhongyan is also completely famous. The Yellow Crane Tower was built in Hubei in 223 AD. In fact, in ancient times, many buildings were built for military needs. Without binoculars and all kinds of high-end equipment, they can only stand at the highest place to see. The Yellow Crane Tower was built under this demand. Of course, the scenery seen on the Yellow Crane Tower is amazing enough. The scenery in Wuhan is all nets. Wang Teng Pavilion is located in Nanchang City, Jiangxi Province. In the Tang Dynasty, Li Shimin named his younger brother Wang Teng and sent Li Yuanying to Tengzhou, Shandong Province, where he developed himself. Li Yuanying lives in Tengzhou and named a building in Tengzhou as Wang Tengting. Later, he went to work in Nanchang. When he arrived in Nanchang, he always missed everything in Tengzhou, so he built a building in Nanchang and named it Wang Tengting. Wang Tengting Pavilion in Tengzhou has long been destroyed, leaving only Nanchang. Stork Tower is located in Yuncheng City, Shanxi Province. Mainly because there are often many storks parked on the roof, it is named Stork House, which is close to the Yellow River? Looking ahead, overlooking the river? This is Shen Kuo's word for the mirage. From these eight words, we can also appreciate how spectacular the scenery around the mirage is. In the Yuan Dynasty, the mirage was destroyed by the war, and now it has been restored on a large scale. These four buildings also have a long history. Literati and poets in various dynasties have written many poems praising them, which are the witness of China's growth history.
