> Why is the bear's name in English the same as "Winnie the
> Feces"?

The character was named after the real life stuffed bear that belonged to the original author's son. The son named his bear after a real life black bear that they saw often at the London Zoo, named "Winnie," and a swan that they encountered there as well named "Pooh."

In the context of the stories, in the first chapter of the original "Winnie-the-Pooh," the author writes an explanation as to why he is called "Pooh":

"...his arms were so stiff ... they stayed up straight in the air for more than a week, and whenever a fly came and settled on his nose he had to blow it off. And I think — but I am not sure — that that is why he is always called Pooh."

"Pooh" is the sound that the bear makes when blowing a fly off of his nose.

I am sorry that English is too complex a language for you to grasp. I am also sorry that you were unable to do research before you went and posted something that ignorantly belittled a classic, beloved and important English literary character.
