堵塞

堵塞 refers to a blockage or obstruction, often used in the context of physical clogging or metaphorical hindrance. It can describe both literal and figurative blockages, such as a clogged pipe or a bottleneck in a system.

The character 堵 (dǔ) means 'to block' or 'to prevent,' while 塞 (sāi) means 'to plug' or 'to fill.' Together, they form a compound that emphasizes the idea of something being blocked or filled in a way that prevents movement or flow.

堵塞 is commonly used in everyday situations like traffic jams, plumbing issues, or even in abstract contexts like communication barriers. It is also used in technical fields, such as engineering or medicine, to describe obstructions in systems or bodies.
