In fact, both statements are correct. The cherry blossoms of Wuda University were first planted by the Japanese army when it set up a field hospital in Wuhan University, in order to alleviate the homesickness of the wounded soldiers.

Then after the Anti-Japanese War, after heated discussion, it was decided to leave the cherry tree as a historical witness.

After decades of ups and downs, the cherry blossoms of Wuda University have developed to the present scale under the careful cultivation of teachers.

Moreover, "the cherry blossoms I sent on the day of the establishment of diplomatic relations between China and Japan" is indeed true. On the campus of Wuhan University, the words "Direct Delivery from Japan" can also be seen on several cherry trees.
