HUH???
WARNING MINOR RANT TO FOLLOW
I don't know about Hung Gar but I believe you should spend a little more time training any style of Kung Fu before you start labeling anything impractical based on a false pretense such as
"most of the attacks were to the body as kung fu was more 'honorable." Kung fu fights are down right nasty if they go all out and there is nothing off limits. Look at any Qinna or Shuaijiao and you will see that whole "honorable" thing go right out the window. And almost ALL CMA styles have a little of both in them.
Knee kicks are big in MOST kung fu styles as are groin kicks. Heck even Taiji blocks the lower body, but mostly with legs and kicks to block incoming kicks. And it attacks the lower body too. Xingyiquan also is BIG on Leg kicks, especially to the ankle and the knee. Bagua, Long Fist, Sanda, Tongbeiquan, etc are no different they all protect the lower body as well as attack it. GO off and fight a Xingyi guy thinking he won't attack the lower body and it WILL get you hurt.. really bad. Or for that matter go off and spar just about any CMA stylist and you will get the same resault.
I am not sure exactly what you are after here but you really need to do a bit more research before you start labeling entire arts based on a little experience in one southern style.
I could do that same with Karate, but it would be VERY wrong but I was INCREDIBLY unimpressed by what I learned in the month (1 whole month) I spent in a Villari Shaolin Kempo Karate school many years ago. But IÂ’m not going off saying Japanese styles are ineffective based on that nor am I saying Karate is ineffective based on that because a month in ONE style does not make me an expert or a judge.
