Lee opens a dojo because he feels like he isn't keeping up with his training. He is hoping challengers will come to his dojo to face him in battle.
In other words,
he’s just been warming up,
،بمعنى آخر، كان يقوم بالإحماء فقط
Mit anderen Worten:
das war nur das Aufwärmen.
Solo te estaba poniendo a prueba.
Hasta ahora solo te puso a prueba.
In altre parole,
 stava soltanto sondando il terreno
Em outras palavras,
ele estava só se aquecendo
