Business & Professional Life: This is the most common context. When an employee resigns, a key part of the offboarding process is the `工作移交` (gōngzuò yíjiāo), or “work handover.” They must transfer all their projects, client contacts, documents, and even physical company property (like a laptop) to their successor or manager.
Government & Politics: 移交 (yíjiāo) is used for significant transfers of power or territory. The most famous example is the `香港主权移交` (Xiānggǎng zhǔquán yíjiāo) — the handover of Hong Kong's sovereignty in 1997.
Legal & Law Enforcement: This term is used when transferring evidence, a suspect, or a case from one department or jurisdiction to another. For example, police might 移交 a criminal suspect to the court system.
Formality: 移交 (yíjiāo) is almost exclusively used in formal, official, or professional situations. It carries a neutral, procedural connotation. You would never use it in a casual setting among friends.
