汉字
用法
- To blockade / seal off / lock down - 封锁边境 (fēngsuǒ biānjìng) seal the border; 封锁消息 (fēngsuǒ xiāoxī) suppress/black out news.
- Applies to areas (military or quarantine) and to information; the 锁 (lock) adds active shutting-out, stronger than 关闭 (guānbì, close).
- Contrast 封闭 (fēngbì), which is more 'closed off/enclosed' without the enforcement nuance.
