The structure “为” is a formal written way to mean “is” or “serves as.” It is often used in news, business, and official writing to identify a person’s role, status, or identity.

“包括……等” is used to introduce examples within a larger category. “包括” means “to include,” and “等” shows the list is not complete. This pattern is very common in formal descriptions and reports.

“由” introduces the agent, source, or responsible party. In formal written Chinese, it often means “by,” “from,” or “under the control/ownership of,” especially in passive-like or descriptive business sentences.

“旗下” literally means “under the banner of.” It is commonly used in business Chinese to show that a company, brand, or organization belongs to or is subordinate to a larger group.

“成立” means “to be established” or “to be founded.” It is frequently used in formal and news contexts for companies, organizations, and institutions. In reports, it often appears with time expressions such as “近日” or “昨天.”
