關於愛，我是個小學生。

the followings are what i learnt from one of the greatest tubers, g scribling, acclaimed and shared by chris the firy eyes:

above the knees, which firstly drive the downswing 
hips smooth rotation, no lunging nor bumpig
lassitimus initiation, left hip down and back, not up nor foward
shoulders swing upward, while shaft down and outside
center of swing arc, lower left of left shoulder
alternative corkscrews
shoulder ball pointing at left heel
target line turns as you swing
spot the full release line
skater's arm drawing
1 degree open putting
where's the start point of a down swing? where's the middle of it?
