error on 4 panel manga, n explain between Yonkoma n Doujinshi

1 of my fren read my blog n pointed tat 4 panel manga is not doujin shi .... is known as
Yonkoma anyway tq 2 him alot n i would explain Doujin shi as well...
Basically Doujin shi are self publish japanese works, either manga or novel (or both at the same time) Doujin shi are usualy writers or author use their own funds 2 publish their works, unlike those mangaka in Weekly Shonen Jump( i will post another blog on this)... they will sell their works mostly on Comiket hoping ppl wil enjoy thier work.... There is 1 anime tat tell a story of how doujinshi ppl work n is kinda funny.... find Doujin Works as they describe how newly amateurs work on their living lolz! anyway really sry 4 de wrong info 4 readers!
