Has the Chinese dubbing TV version of Detective Conan been deleted from the original cartoon?

Of course there are deletions. Every cartoon in MS is deleted more or less when it is changed to animation.

However, you have only watched more than 20 episodes, and there are more than 500 animations. What you said about Xiaolan confessing to Conan when she suspected that Conan was Kudo and taking a bath with Conan are all at the back of more than 20 episodes. You can take your time.

Lan suspected Conan three or four times. Every time she wants to be exposed, someone comes to help Conan, even Kidd (see the ending point of the theatrical version)

Looking back on Conan's confession, it was in the theatrical version: later, Lan was always worried about whether Conan really loved her (after all, she was a little P child in her eyes). In the movie, there was also a clip in which Bumei said that Conan liked Lan, which was very funny.

Bathing with Conan was in episodes 27 and 28, when Richard Moore's classmates were going to kill people (I think it was this episode, it should be). Lan washed Conan's hair and wiped his back. It seems that Conan also saw Lan's body with a nosebleed.

There are many funny things, almost every episode has Conan's sneer.

See if you understand. The later the better.

I hope I can help you. I am the real conan fan.
