The development is not big, and the administrative department belongs to the supporting auxiliary department in the enterprise, and its status is not high. Even the so-called glamorous human resources department is the same, belonging to the auxiliary department, not the core department. The core of an enterprise is R&D, production and sales. If you are a master of science and engineering, you can find production and research and development. This society still needs skilled people, and the older you are, the more valuable you are. Find an administrator and work for five or six years, and there will be no development. The company will find undergraduates younger than you. Why? Cheaper than you.
