There are a lot of terminologies in karate, and we are sometimes
using without knowing the correct usage.
e.g. Gedan barai (sweep) and Gedan uke (block)
Gedan barai; like the 1st movement of Heian shodan
--> The other hand touches on the body.
Gedan uke; like the 1st movement of Jion
--> The other hand does not touch on the body.
