Subtitles is too difficult - translating every word for word and using software to add subtitle.
I know because I did it before.
So I will just summarised rather, and you guys can go and reply.
Ma Long - serving more with body weight.
So in other words a lot of his power comes from his feets and movement of the body.
His had just focus on the spin
So overall it is a soft/small movement from the eyes of the opponent
Zhang Jike does something similar but uses a very late action during the contact point
I saw this video a while ago, so just saying from memory
I will rewatch it later and summarise even more
Edit, here we go:
Ma Long
1) From toss, his body weight usage is very good - so he is able to toss straight and lead to a more accurate contact point (ball isn't all over the show)
2) Ma Long serves a lot to the FH short mini triangle (look at 1:20), then continues with a FH to mid of the table (1:40), then follow by a long ball (under or top) into the bh corner
Takes about FH serves, parallel to the table
Talk about the grip and using 2 fingers, majority the thumb pressure.
Ma Long focus a lot of his first bounce - close to net, so it can be nice and short
Then the control from his toss comes from the body weight and not just his wrist. This will give him more consistancy
To practice - don't practice too fast. Take enough time for each step
Then talks about the contact point with the decending ball. Best is to contact it at your chest height, so you are able to control it more with yoru body weight
Zhang Jike
He is different because his contact action is "sudden" or late, thus can surpise his opponent
Most people will feel his serves are more spinnier, and his serves is more tricky
07:30 - comparing to the FZD and ZYL, using his arm and wrist to change all of the sudden at the last min. compared to others where the action is bigger and earlier.
ZJK focus on two different spins and used them side by side. FH short under spin or FH reserve pendulum serve.
He suggest that we practice serve and get the feeling of each ball at the time. Also use our body weights better.
So this is what he suggest for beginners to learn serves.
Also we need to consider how we serve, the spin and how we continue the next stroke, so we can link the serve to our strength (strong stroke) and not distance from it.
