I read some history about sanda, it seems that sanda is a copy
of muay thai, after the chinese kung fu masters got beaten soundly
in thailand in the famous martial arts challenge in the
1970s.
The name "sanda" is also something that the communist govt. came up
with, the original name was san shou i think. But sanshou in the
past looks nothing like what it is today, sanda today is a pure
copy of muay thai adding some shuai jiao throws into it. I have
watched training clips of the sanda team in china including liu
hailong the best sanda fighter, and it looks like muay thai
training.
The commie govt., because of nationalistic pride, must resort to
copying without even attributing the source.
If you will watch the sanda matches on youtube, it is full of
propoganda. Esp. when they fight against the thais. The
commentators are saying all kinds of good things about their
fighters and putting down the other fighters. When the sanda
fighter loses, they will make lots of excuses (he hasn't been
training, he just had a bout of sickness, etc. etc.). I just want
to vomit when I hear some comments that they make.
