This is my classmate. From the picture, what does his mother do? White collar?

She is a well-paid white-collar worker, because she says she can buy fashion at will, but fashion is not cheap and can be changed quickly, which is not a small expense. Her picture is in the office. The space is not small, the lights are bright, and there are office supplies that can't be seen clearly, such as telephones. She is also well dressed. It should be a management level, and her salary should be not low.
