Where to learn Feng Shui?

I don't know what level of teacher-apprentice relationship you are talking about, whether it is an ordinary teacher-student relationship or a traditional relationship of blood and kowtowing to teachers.

However, I think,

First of all, there are many free teacher courses online. You can learn about the level of teachers through free courses.

Secondly, you should master more basic knowledge.

Then, choose a teacher you trust and attend the teacher's offline course.

As for the apprentice, it depends on fate.
