Couple of ways:
1. As the clutch begins to bite, the engine RPM will drop.
Watch the tachometer to see when this happens.
2. On a front-wheel-drive vehicle, as the clutch begins to bite,
you'll notice that the rear of the vehicle will squat slightly due
to engine torque. You should be able to feel this.
When you notice one or both of these happening, release the
handbrake, give the engine a bit of gas, and release the
clutch smoothly all the way. Very simple, really! 
Haha is it? Thanks for the advise! I will try that during my
lesson. But frankly speaking, manual vehicle quite ma fan, nowadays
on the road, almost all the vehicle is in AUTO le.
