Common Collocations

- 封信 (fēng xìn): to seal a letter

Notes
When using 封 with letters, it is common to see it combined with 信 (letter) or 邮件 (mail). The measure word 封 is specifically used for letters or documents, not for packages or parcels.
In contexts like police or security, 封 can mean to seal off an area, indicating restriction or prohibition of entry. This usage is more formal and often seen in news or official announcements.
Avoid confusing 封 with 包 (bāo), which means to wrap or package, as 封 emphasizes sealing or closing tightly, especially for letters or official documents.
