During the Japanese invasion of China, Wuhan fell, and the old residence of Wuhan University became the headquarters of the Japanese invaders. The Japanese army planted cherry blossoms, the national flower of Japan, on the hillside of Laozhaishe, which became the beginning of cherry blossom in the cherry blossom garden. After the establishment of diplomatic relations between China and Japan, Japan presented a batch of cherry trees as a witness of Sino-Japanese friendship. The state planted these cherry trees in Wuhan University and Tsinghua University respectively. The cherry trees planted by the Japanese invaders were neglected after years of war. Most of the existing cherry trees in Wuhan University are cultivated and planted by the Landscape Department of Wuhan University. The cherry blossoms in the cherry blossom garden of Wuhan University are not only the famous beauty today, but also the testimony of the sufferings in China's history.

It is generally believed that the main purpose of Japanese planting cherry blossoms here is to alleviate the homesickness of a large number of Japanese wounded soldiers who live here to rest, but also to show off their martial arts and long-term occupation. Therefore, the first batch of cherry blossoms in Luojiashan can be said to be evidence of Japan's invasion of China and a symbol of national humiliation; It is also the origin of cherry blossoms in Wuda University today.

According to the memories of the older generation of gardeners who stayed on campus at that time, the Japanese army planted no more than 30 Japanese cherry blossoms in Wuda that year, mainly distributed on today's cherry blossom avenue. After the victory of the Anti-Japanese War, Wu Da 1946+00 returned to Luojiashan in June; 1March, 947, teachers and students of biology department of Wu Da University observed that there were 28 cherry trees in full bloom on campus, which were evenly distributed between the three archways of the old Zhai She and in front of four gates on both sides (there were 7 trees in front of each gate). At the beginning of 1949, it was suggested to cut down the cherry tree. At that time, the commander of the national army stationed in Wuhan was rebelled by the China underground party. After surrendering in March, he said that Wuhan University was a treasure house, and everything in it should be preserved, so the cherry trees were preserved.
