Since I took kung fu I'm not going to list the obvious like chain punches are awesome and the horse stance builds kicking power, etc.
When I usto watch people grapple and saw someone who was mounted or side mounted I usto believe those people were pussies because they couldn't just power out of it.
I also usto believe that throwing a guy on his ass would be easy, and usto practice throwing imaginary opponents in hypothetical situations.
This isn't related but I kicked my dog by accident once when I was younger practicing spinning crescent kicks. I also usto practice punching as close to my cat as possible without hitting him. After a while he didn't even flinch, just gave me that "you're a fucking LARPin' piece of ****" look.
I usto believe that by practicing my forms with forceful movements I would be increasing my punching power. This might have helped a little as it got me usto throwing a lot of energy into a technique in as little of time possible but of course there are better methods for doing so.
I usto believe in throwing a lot of back fists as you were striking and potentially blocking a shot at the same time. This sounds nice in theory but in application if you're not fighting a complete tool it tends to not work.
I usto believe my Sifu was hiding the grappling component of kung fu from me and all the applications to the forms until I realized that he knew nothing of either. He is a decent pseudo-kickboxer but I didn't see him use any of his kung fu in the six years I studied under him.
I usto believe in the knee stomp and standing elbow snatch and break.
There's lots more but that's all I feel like posting for now. In short taking a bullshido martial art when you're in the "I'm six feet tall and bullet-proof" stage of development just isn't healthy, mmk?
