There are many passwords, all in Korean. The most basic thing is to stand at attention, which is expressed in Chinese as: stand sideways (read faster), then: salute, Gree (Korean) (read faster), start: West (Korean), resume: climb stairs (Korean), and prepare: Chinese pronunciation seems to be not much different from Chinese pronunciation. These are basically passwords. Mainly listen to the coach's password, and then model the sound. There may be subtle differences. If you really want to learn standard pronunciation, you'd better find a better coach or learn a little Korean. Learning a little Korean is also necessary for Taekwondo.
