You are welcome. :-) Yes, I think you can translate jingjie into "realm", since it is the nearest.

I have googled but still haven't digged out a satifying answer. Jingjie is a philosophical term that only makes senses in chinese cultural contexts, so it is difficult to find a perfect match in English. Here's a traslation from the Contemporary chinese philosophy: "Late Qing Dynasty scholar Wang guowei had once stated that, all those have been highly sucessful have experienced three modes of jingjie: 1.The first stage. My colthes grow daily more loose, yet care I not.For you am I thus wasting away in sorrow and pain. 2.The second stage. Last night the West wind shriveled the greenclad trees. Alone I climb the light tower to gaze my fill along the road to the horizon. 3.The third stage. I sought her in the crowd a hundred, a thousand times. Suddenly with a turn of the head [I saw her], that once there where the lamp light was fading.

Anyway my try is "boxing practise is also in the same way."

你要问反身动词都是及物动词是吗？不尽然。反身动词仅表示所实施的动作和行为作用于这个行为的主体本身，即宾语为主体本身，大多数情况下都是及物动词。但也可以举出一些反例，我查了一下语法书: 比方：Die Mutter wäscht sich. （可及物可不及物） 还有动词比方sicherholen，sich erstrecken 不及物
