The origin of Sun Yat-sen Mausoleum in Nanjing?

It's the Sun Yat-sen Mausoleum, with no history. Sun Yat-sen Mausoleum/KLOC-0 started construction in June, 926, and the main body was completed in June, 929. 1March, 925 12, Sun Yat-sen died in Beijing. After Sun Yat-sen's death, his body went through hardships, and only under the careful protection of the body did it survive. It turned out that Sun Yat-sen had ordered the funeral ceremony and coffin style to be modeled after Lenin's so that people could pay tribute to the remains. However, when Mr. Sun died, the FRP coffin presented by the Soviet Union could not be delivered in time, so it had to be temporarily placed in an integral glass coffin and parked in the stone tower of Biyun Temple in Xiangshan, Beijing. 1925 when the Soviet government sent the FRP coffin on March 30, Sun Yat-sen's body had been dead for more than half a month. Due to improper anti-corrosion measures, the body could no longer be seen by future generations and had to be buried. On May 26th 1929, the body was moved from Beijing to Nanjing. At that time, a copper coffin ordered from America was placed about 5 meters below the recumbent statue. In the late period of the Liberation War, Chiang Kai-shek wanted to move the remains to Taiwan Province Province, but he gave up because the bombing of the tomb would inevitably cause damage to the remains, and finally kept them safely in Sun Yat-sen Mausoleum.
