Why did the river god become the representative of the oriental god in 100 thousand cold jokes 2?

Xiao Shenyang is a subordinate of the oriental goddess Nu Wa. His daily job is to find things that fall into the river. He is a slow and wordy male god. Nuwa is often annoyed and disliked by Nuwa. Although he is slow in talking and doing things, he is soft and optimistic, and often solves problems for the Qiqi team at critical moments. He is an indispensable main player in the team.

Because the background of the river god's first appearance in the "Ten Lengs" was ancient China, maybe the producers at that time thought it was more appropriate to put the woodcutter in the traditional background of China, so they directly turned the river god into the river god of China. In a sense, this is the producer's fault, but it seems that only two people have answered this question so far. When the animation itself shapes the characters just right, not many people will care about the source behind them.

There is also a saying that the river god actually comes from the woodcutter and Hermes in the third volume of Aesop's Fables, and the true face of the river god is Hermes! Zeus's illegitimate child, and Athena turned out to be brother and sister! So it seems that CP must be dismantled. As for why he became an oriental river god? I think ten cold and three cold may have an explanation.
