Is there a Chinese word for the Japanese 気合 (kiai), the sounds ("Hi-yah!" etc.) made when performing martial arts?
Here's a Zhihu question about kiai in kendo (劍道). In the realm of Japanese martial arts, it looks like Chinese would just character-transcribe the word as「气合」.



Note that「気合」is specifically a Japanese term, and is used for a host of other meanings in Japanese (breathing, martial spirit, etc.) , so I would say that using「气合」in Chinese in a martial-arts related sense is not appropriate for anything outside of Japanese martial arts. The closest Chinese-language term for martial spirit would be something like「气勢」, and this doesn't necessarily point to any shouting.


  「气合」is also a classical Chinese term meaning agreeable sentiments/inclination.
