When did Yueyang Tower collapse?

At the end of the Eastern Han Dynasty, Lu Su, a general of Sun Quan, was ordered to guard Baqiu, drill the water army, and build the ancient city of Baqiu in the dangerous area connected with the Yangtze River in Dongting Lake. In the 20th year of Jian 'an (AD 2 15), Lu Su built a military reading building on Baling Mountain to train and command the navy. Yuejun Building stands on the shore and enjoys a panoramic view of Dongting Lake. Various pictures (2 pictures) of Yueyang Tower can be seen in the lake, with extraordinary momentum. This Yuejun Building is the predecessor of Yueyang Building. Yuejun Tower was called Baling Tower in the Jin Dynasty and the Southern and Northern Dynasties, and Yueyang Tower was not called Yueyang Tower until the Tang Dynasty. [1] In the fourth year of Song Dynasty (AD 1044), Teng was banished to Yuezhou, and the Yueyang Tower at that time had collapsed. In the fifth year of Song Dynasty, Teng rebuilt Yueyang Tower with the support of the people. Yueyang Tower rebuilt by Teng was destroyed in the 11th year of Chongzhen in Ming Dynasty (1April 639) and rebuilt the following year. Many repairs were carried out in the Qing Dynasty. In the sixth year of Guangxu reign in Qing Dynasty (1880), Zhang Derong, the magistrate, carried out a large-scale renovation of Yueyang Tower, and moved the building site more than 60 feet. In the history of 1700 years, Yueyang Tower has been repeatedly repaired and destroyed, and repeatedly repaired and built. After many vicissitudes of life, it has been destroyed and built repeatedly, and there are more than 30 traceable repairs in history. After each renovation, "some praises are hung on the eaves of the ice pavilion, and the literati climb high and wander"; ; At the time of destruction, "the waves were overwhelming, and the poet bowed his head and took a deep breath" (Zhang Derong rebuilt Yueyang Tower in Qing Dynasty). By the end of the Republic of China, the building was dilapidated. After the founding of New China, the Party and the government cherished Yueyang Tower very much. The people's government allocated funds for the maintenance of Yueyang Tower for many times, and also built Huaifu Pavilion and stele gallery, and rebuilt Sanzui Pavilion and Xianmei Pavilion. 1983, the State Council allocated special funds for a one-and-a-half-year overhaul of Yueyang Tower, with the aim of "repairing the old as the old" and copying and updating the decaying components as they are. In May 1984, 1, Yueyang Tower was overhauled and opened to the public. The restored Yueyang Tower retains the scale, style and most building components of the Qing Dynasty.
