Meaning

The structure (包括)⋯⋯在内 is used to explicitly include someone or something within a group or count. It emphasizes that the mentioned item is part of a larger set, equivalent to 'including' or 'comprised of.'

This pattern has two main arrangements: the included items can appear before 在内 with or without 包括 preceding them, or 包括 can introduce the items with 在内 closing the phrase. Adding 在内 makes the inclusion more emphatic and definitive compared to using 包括 alone. The pattern is more common in formal and written Chinese, appearing frequently in news reports, official statements, contracts, and academic writing. It can specify either people or things. When a number or quantity follows, 在内 helps mark exactly what is being counted.

Examples

1. 包括税费在内，这套房子总共花了三百五十万。 Including taxes, this apartment cost a total of 3.5 million.
2. 算上他本人在内，整个团队一共有十二个人。 Counting himself, the entire team has twelve people.
3. 这次裁员涉及多个部门，包括市场部在内。 This round of layoffs involves multiple departments, including the marketing department.
