This question is very good, let me answer it

1. There are currently two versions of Doraemon. Old version and new version. The old version was in black and white. The new version is divided into two versions. One is the Dashan version. This is the version we are most familiar with. Since the original voice of Japan's Doraemon was dubbed by Oyama Xiandai, it is called the "Oyama version". 2 is the paddy field version. The voice actor who plays Doraemon is Mizuta Sangui, so this series is called the "paddy field version".

2. Everything on TV is the Dashan version. The paddy version has been introduced in China. But I don’t know where to look. Specifically from episode 1 to episode 1984. Including the theatrical version.

3. The Dashan version has 1984 episodes (including the theatrical version). The paddy field version is unknown. The paddy field version is currently being updated. The Dashan version is finished.

4. TV*** has more than 2000 episodes. The theatrical version has 32 episodes.

5. Doraemon's ending means the ending of the famous Japanese comic "Doraemon". However, so far, except for the original author Fujiko F. Fujio's suspension of serialization and the broadcast of all previous episodes by TV stations, almost all works have been circulated online. Despite this, the author still stated before his death that "Doraemon" has no substantial ending, and with the The serialization ended after his death, and the story of "Doraemon" is still continued in the form of animation. There are three official versions, all of which became unofficial endings when the series was restarted.

①Showa 46 version Showa 46 (1971) version, because people from the future go sightseeing in the present, causing trouble to modern people, the future government legislates to prohibit time travel, so Doraemon must go back .

②Showa 47 version Showa 47 (1972) version, Shixiu believes that if Doraemon is always by Nobita's side, Nobita will achieve nothing because he relies on others for everything, so he wants Doraemon to come back. future. So Doraemon pretended to be sick, but then Nobita was very worried, and Doraemon told Nobita the reason why he really wanted to go back to the future. Nobita said he thought so too, and asked Doraemon to go back to the future. From then on, Doraemon used Time TV to watch Nobita working hard every day. The Doraemon broadcast on Nippon Television in Showa 48 (1973) was based on this script and showed the last episode of Doraemon.

③The Showa 49 version was drawn in the March issue of Showa 49 (1974). Doraemon must go back to the future one day. After Nobita defeated Fat Tiger on his own, Doraemon went back with peace of mind. . Because she was not popular at the time, Fujiko originally wanted to end it. But out of his love for Doraemon, he drew "Doraemon Returns" in the next issue. The content is that Nobita was cheated by Fat Tiger on April 1, and he decided to drink Doraemon and leave it to him. "Lie 800" potion, because Nobita said: "Doraemon will not come back" and finally reunited with Doraemon. "Goodbye, Doraemon" is included in the stand-alone volume 6, while "Doraemon Returns" is included in the stand-alone volume 7. In fact, they are just a section of the story, far from the ending. In addition, this plot was adapted into the appendix of the 1998 theatrical version of Nobita's South China Sea Adventure: Doraemon is Back, but due to the film's misplacement or misappropriation, it was also mistaken for the regular ending, ignoring the fact that it still continues to be broadcast. TV animation version.

As for your "Which episode is it from?" I don't understand it.

It's purely hand-made and I hope you will adopt it
