yīcùn xiǎo, yīcùn qiǎo
yīcùn duǎn, yīcùn xiǎn
One inch smaller, one inch (more) skillful
One inch shorter, one inch closer
~ an old Chinese saying
If your sword cuts are an inch longer, they will have more power. However, if they are an inch smaller, that is more skillful. Then the distance to the duifang is an inch shorter, and you are an inch close to land a blow.
Note that the last word in this saying, xiǎn, is typically translated as danger in common vernacular Chinese. It can however also mean to be near as in anear miss or a close call.. The overall structure of the saying is one where a specific condition leads to a improved result. Following that structure, the distance being an inch shorter, places the swordsman in a better tactical position, one inch closer to landing his or her blow. Certainly, that is also a more dangerous position (for both swordsmen). However, if one has deflected properly, leading the duifang’s weapon into a void while maintain tip control, so that one’s sword is aligned with its target, then in this dangerous position, there is a strategic opportunity.
