Most wuxia battles occur in places where there's plenty of elbow room - on an open field or in a room large enough wherein movement is not greatly restricted. Sometimes, wuxia fighters who meet in a small space might even move out of the space to gain more elbow room for fighting (e.g. fights that start in restaurants might spill out into the street).
What are some memorable wuxia fights, however, that are notable for their lack of elbow room for the combatants...where in addition to fighting the enemy, the fighter also had to fight the walls of a confined space.
Here are a few that come to mind:
1. Gwok Jing's struggle against Leung Tze Yung's big snake inside the well at Leung Tze Yung's manor during LOCH.
2. Sing Kwun and Tse Tsun's climatic final battle during HSDS in the small pit underneath Shaolin.
