Are there any famous architectural design enterprises or units in Beijing? I want to practice in those places and accumulate some experience.

If you can't enter the architectural design unit, you can go to the interior design unit.

Plus, even if you don't get paid, you can't get in. You'd better go to the interior design unit.

If you have to go in and experience it, find a small studio for several people, which may require odd jobs.

As long as it is a formal architectural design unit, it will not want people who are not in this major. Undergraduate students, undergraduates and junior college students majoring in architectural design don't want a lot of internship treatment and there is no shortage of people.
