The shot in MMA (aka the double leg)

[Happy Tiger]

The

1. ?(Tuo) – chin,
2. ?(Wu) – face,
3. ?(Feng) – Throat,
4. ?(Mo) – forehead,
5. ?(Tong) - shoulder,
6. ?(Gai) - upper arm,
7. ...

are all good contact points for "push". Since one will need one hand to push, Chinese wrestlers don't like to use both hands to grab the leading leg.

Nice...one oh one in Hapkido too
