Is there a grave under Wanshou Mountain in the Summer Palace?

Wanshou Mountain is the remaining vein of Yanshan Mountain, with an altitude of 58.59 meters and an altitude of 108.94 meters. In front of Kunming Lake, in the seventh year of Hongzhi in Ming Dynasty (1494), Xiaozong's wet nurse helped Mrs. Roche build a garden temple in front of the mountain. In the early Qing dynasty, it was used as a forage field for raising horses in the court. In the 15th year of Qianlong (1750), to celebrate the 60th birthday of Empress Dowager Cixi, yanshou temple was built in the former site of Yuan Jing Temple. The following year, the mountain was renamed Wanshou Mountain. Moreover, the soil for developing Kunming Lake will be piled up on the mountain according to the needs of the original layout, so that the east and west slopes will be relaxed and symmetrical and become the main body of the whole park. The building was built on a mountain, and the existing one was rebuilt by Cixi after the British and French allied forces burned down. From the "Yunhui Yuyu" archway at the foot of the mountain, through Paiyun Gate, Ergong Gate, Paiyun Hall, Dehui Hall and Foxiang Pavilion, to the wisdom sea at the top of the mountain, a rising central axis is formed. Today's Wanshou Mountain was named Wengshan in the Yuan Dynasty. Legend has it that an old man dug a stone urn full of treasures on the mountain and got his name. There is a lake called Wengshanpo in front of the mountain. A.D. 1292 (in the 29th year of Yuan Dynasty), scientist Guo Shoujing dug Tonghui River, and collected the spring water from Changping and Xishan into the lake and injected it into the palace wall to help transport water. Wengshanbo has become a reservoir for water use in Beijing. From this to the Ming Dynasty, many influential temples appeared around the lake, especially the "Dacheng Tian Shu Temple" on the northwest bank of the lake, with the largest scale and magnificent architecture. The white marble diaoyutai extends into the lake, where emperors of Yuan Dynasty often go boating and fishing.
