Japanese kuydo shafts and korean bamboo shafts

Hello:
so many person love and paly Japanese kuydo shafts and korean bamboo shafts,but in china,no live their bamboo specie,i personal think china tonkin bamboo is thicker wall and more stuff than japan and korean bamboo sepcie.and their bamboo live in warm or hot area which naturally very bent and they must make 1 hole when heating,their bamboo wall is thiner and easy to break when heating,china tonkin is thicker wall and no need to make 1 hole when heating,of course you can repeat to shoot them more time than japan and korean bamboo arrows,in fact japan and korean learn chinese bamboo arrow shafts making many years ago,but they learn just surface skill 1000years ago,and still do them by hand,so,their price is quite higher than mine,my bamboo shafts is tonkin which live on 800-1000meter above higher montain:more straight natural living and we polish the nodes by machine,not by hand.i have to say japanese and korean make good quality bamboo arrows,i plan to make similar kuydo or korean bamboo arrows,if somebady tell or show me their detail photos and size and last nodes(near small end which put fletch) distance?so,i can offer many good quality or similar bamboo arrow shafts("kuydo or korean bamboo") for normaly user for traning and no worry to break so expensive bamboo arrow,japan and korean 's price may be only for rich player,not for normally people,i want to let all person can buy my "kuydo or korean bamboo arrows",but little heavier and more repeat shoot times for their noraml training.
i need janpan and korean bamboo arrows detail photo of diagram size marked ,just for 99% normal person player,not only for rich people.i guess chinese bamboo arrow will be very popular in future for its fast speed shoot and very stiff and fastest vibrition return speed(snake action) and beautiful art looking.
before producing,i need study them very carefull,ortherwise i will lose a lot of money and time for such risking.
