神经
How to Understand
神经 (shén jīng) refers to nerves in the body, specifically the network of nerve fibers that transmit signals between the brain, spinal cord, and other parts of the body. It can also be used metaphorically to describe a person's sensitivity or emotional state.
The character 神 (shén) originally meant 'spirit' or 'god,' while 经 (jīng) means 'main artery' or 'classic.' Together, they literally translate to 'spiritual arteries,' reflecting the ancient belief in the body's vital energy pathways.
In daily use, 神经 is commonly found in medical contexts, but it can also appear in idiomatic expressions, such as 没有神经 (méi yǒu shén jīng), meaning 'to have no nerve' or 'to be fearless.' Understanding this term helps learners grasp both physiological and emotional aspects of Chinese language and culture.
