Udon at that time had weak flour and no Koshi,it seems that it was like Switon.
Udon since the legacy went so eaten into the hot broth in Fukuoka.
This is because there is no way to eat noodles in hot broth in China,Udon is a unique culture grow and developed in Japan and Udon culture development continues even today any place, example Sanuki, Ise , Osaka , Fukuoka.
