Ip Man 4 recent release is not the original ip man 4

 1. The movie is part of an art project.

2. In one part, a fighter touches a DJ record pad with his foot. The words of 

"Ike and Tina Turner are played."

3. There is a secret city.

4. He and another master have dialogues in the local paper.

5. "I am the teacher" and "I am the student"

6. His wife sells the baby/son. Ip man has nothing more to do with her.

7. His nemesis is Ice Pick Man who uses an ice pick to win ring fights.

8. Ip Man, the other teacher, and the students defeat Ice Pick man and his group

using reason and martial arts.

9. A film of Ip Man practicing on a wooden "doll" is part of the film.

10. Ip Mans passing is shown in the film through indirect referencing.

11. Ip Man does not visit America. Bruce Lee visits him. Ip Man rejects Bruce Lee

 for some reason.

Why is that version no longer available.

I believe, Wilson Yip and Raymond Wong, that you also saw the original Ip Man 4 which was an artistic film

by either a school in Hong Kong or a school from Mainland China.
