"Doraemon" (Robot Cat) is loved by many readers in the mainland, but there are serious viewers, but some interesting phenomena are found in some small details of this anime when it is broadcast in Japan, and the elementary school hall and NHK.
Doraemon was released in Japan in April 1979, but in episode 1, a mysterious person appears among Nobita Nobita, Yasuo, and others.
The mysterious little friend is tall and thin, and obviously knows Shizuko, Yasuo, Nobita, and Xiao Fat, and has not said a word from beginning to end.
From the beginning of the first episode to the end, this little friend is mixed with several people, but his name is not given from beginning to end.
It was not until the end of the 1st episode of the 2nd episode that it was found that the little friend had disappeared, and the producer did not explain too much, but it was speculated that it was very likely that at the beginning, it was set up as a group of 5 people, but I don't know why it was later adjusted to 4 people.
When the anime of the 11th episode of volume 1 was released in Japan, because the title of the phrase was "I have to get a perfect score anyway", some attentive viewers recorded the animation and studied Nobi's homework problems.
This frozen picture is exactly one of Theoss' problems that Nobi has done, only to see that the next nobi is answering a very difficult physics problem, and the answer is still a string of German.
This incident caused an apology from the producers at the time, not only nhk, who played the animation, but even the copyright owner, the Elementary School, who also stood up to apologize to the audience.
