The use of chi sao is mainly to teach you what to do after you've defended against the incoming attacks and you've closed distance with the enemy, it trains positions that you can recognize when in an actual fight. If you cannot get into or keep chi sao distance with the enemy then you lose but that's true of all other martial arts and sports: if a boxer can't get close to a taekwondo practitioner then he loses, if a jiu jitsu guy cannot get into grappling range with a boxer then he will lose, etc.
First of all...welcome to the forum.
Second, what I got from your post is that your wing chun ONLY works in chi sau range. Is this accurate?
In my training and opinion good wing chun has an excellent distance game when utilized properly and using good timing for entries. Problem, as I see it, is most don't practice the outside game enough to gain the need skills to set up entries. Much of the drills associated with both the sword and pole learning give insight to required skills for playing the outside game into the inside close range and back out. Because of that what is more often than not seen is the WC person just rushing in with their arms extended out in front of them and getting punished for it.Thanks. The way i see it, wing chun was made for chi sao range, why else would the second form be called "closing the bridge" (getting close to the adversary)? Wing chun wasn't made for fighting at jabbing/kicking distance which is why you see so many videos online where the wing chun guy loses to such opponents because he fails to close the gap. Wing chun used at that distance becomes bad kickboxing
