The specific arrangement of internship may be different due to the company's policies and job requirements. Can't directly answer "Does Beijing chain home internship need to go to the suburbs for training?" This question.

But generally speaking, during the internship, the company may organize some training activities to help interns better understand the company's business and improve their skills.

If the company has a training center in the suburbs or other places where interns need concentrated training, it may need to go to the suburbs for training.

I suggest you consult the relevant person in charge of Beijing Chain Home Company or the Human Resources Department for more accurate information.
