Bushi Matsumura created both Naihanchi Shodan and Nidan from a kata called Naifanchi that he got from a Chinese Master named Ason.
Some believe either Itosu or Choki Motobu made Naihanchi Sandan. Naihanchi Sandan is not a Matsumura kata, passed down other Shorin
lines. Funakoshi called Naihanchi by the name Tekki, meaning "Iron Horse", which refers to the stance used in it. "Iron" refers to
its strength and stability. "Horse" refers to the fact that it resembles a man riding a horse. There is more than one possible meaning
for the word Naihanchi, and they are both very plausible. The pronunciation of Naihanchi was originally Naifanchi, because that is
the way it was pronounced in
Kihon Bo Ni Kihon Bo Sandan Shihonuke Choun no kun
is a series of 7 movements. The kata reviews the basic bo blocks
is a series of 18 movements. The kata reviews

movements.
It is a four directional bojitsu defending and counter attack bo (kun) kata.
CH'Oun is the name of the
Ryu family / Master who created the kun kata.
So we can break down Choun No Kun as: Ch'oun: family name,No: of,
Kun: Bo Staff. So we
can define the Katae as the Bo Staff kata of Choun,
or the Staff technique of the Master Choun family.
