China's poems are abstract, implicit and restrained, while Japanese chorus is concrete, bold and direct.
As for the identity of the authors, the authors of Japanese Chinese poems are mostly aristocratic children of royal bureaucrats, who are more exposed to China culture, so their Chinese poems are similar to those of China, but the authors of Hehe songs are different. There are many unknown singers who may not come from the upper class, so they can better integrate the Tanabata legend into Japanese folk.
From the author's point of view, China's poems are mostly in the third person, while Japanese songs are mostly in the first person, in order to be closer to life;
There are also some shadows about Ji's ancient Japanese myths in He Song, which can be said to be the product of the fusion of Chinese and Japanese legends.
