Zhang is aggressive in her jabs & quick punch attacks and she's smart enough to avoid punches to her face. Where as the Japanese lady is more on take downs as in Judo besides punches. The Japanese lady could reserve her energy and managed to continue fighting despite she's bleeding. Her mistake is she thinks she can endure better by allowing herself to tank damages and punches from Zhang in order to defeat Zhang by judo takedowns. She ended up bleeding more. If you see Legendary Muay Thai fighter Buakaw who have defeated many Chinese & Japanese fighters , he knows when to attack and when to avoid his rivals' attacks and throw in forward kicks to belly to avoid enemies to get close to him and lastly elbow strike the opponents in the head and flank attacks.
