gzcs

Could you clarify what “gzcs” refers to? The term is not uniquely defined and may denote different things across domains (technology, organizations, standards, etc.). If you specify the intended domain or the exact entity, I can draft a concise, neutral wiki-style article (under 300 words). If you’d prefer, I can also provide a short disambiguation-style stub that notes that “gzcs” has multiple potential references and requests further details.
