I suck at throws, and I still haven't had a good chance to learn them well yet, but I do have a bunch of takedowns that I use. Some of them may be considered Ving Tsun takedowns in their own right, my sisook once showed me how he took down people with his Ving Tsun, but I didn't really understand what he was doing until getting the opportunity of drilling takedowns while cross training in Penjak Silat.
Biset Luar - The person I cross trained with actually learned from the sifu in this video, and I find it to be a trustworthy explanation.
Biset Dalam - This is basically redirecting a strike and sweeping out the lead foot of the opponent and moving in to attack. It doesn't take em down like biset luar, but it breaks their base and if you can pull it off right it does make the other person fall back just because of how they get uprooted.
Poora - Think about hitting someone with a back fist to the neck/head and using that momentum to somewhat grab the neck and pull the guy's head down while controlling one arm so you kinda twist him upside down. That's the best I can explain it at the moment, but it's a common move in many martial arts.
There were also one other silat takedown that I use sometimes, but not often. I dont know the name for it but it's basically getting wrist control (optimally with both hands) and stepping far past the opponent into a bow stance/gong ji mah. The sudden drop happening behind the opponents body brings him down fast and if you whip the arm up right after it's easy to set up an arm bar silat or bjj style.
There are also some ways I learned to take down in Ving Tsun but I think are common in other arts
One is really similar to aikido (according to my friend) but it's basically a takedown where, lets say, you pak or parry a jab from the outside and just use your body and weight to kinda swing your other arm on the inside (in between his arms) around his shoulder area downwards.
One takedown is one where the set up is having a grab on one arm from the outside while doing a back fist or any move that puts your kiu/bridge across the front of the person's neck. Then you just pull the arm that you're holding while using the other arm to kinda push across the neck while shifting to the side and adding downward pressure with the arm across the neck. Sometimes, especially with people bigger than me, my shift will break their base but not take them down, that's where I follow with my staple takedown...
...where the goal is to do a fast but soft kick to the back of the thigh/hamstrings area using the side of my foot. Then I slide down and my foot rests at the knee cap above the calve, from here I just step down, (not to be confused with kicking the back of the knee). It's the one way of taking someone down that I can demonstrate on anyone (well unless the guy can just kick my ass, i need a fighting chance lol). I've never done this just because it would be to rough for the way I spar, but once the knee of the opponent is brought down, this take down can technically be a throw because you can just slam the body down into the ground by sinking and applying pressure to the shoulders/torso. At the angle you end up in, it's unlikely that the other person can resist any pressure to their broken structure and bent body.
I really want to train some Judo and Shuai Jiao to get familiar with the art of throwing, I think it's so cool but I dont know it at all except when learning a hip throw in a brazilian jiu jitsu class, and that was one day and I still suck at it lol.
Everybody wants to go to heaven but nobody wants to die...
