When Geely Panda is engaged in 1 gear, gently feed the oil to 2000 rpm, release the accelerator, step on the clutch, and suddenly the number of revolutions rushes to 3500 rpm.

This may happen to you if you release the accelerator and press the clutch at the same time. Because the throttle opening of the engine at a certain speed during normal driving is actually greater than the throttle opening at this speed when the engine is idling. So, if you release the accelerator and press the clutch at the same time, it is possible that the accelerator has not been released and the clutch has been pressed in the process. At this time, there will be excess power and the speed will increase.

So don't read many articles on the Internet that teach novices to "release the accelerator and step on the clutch at the same time", which is actually easy to cause the speed of stepping on the clutch to increase. The correct operation is to step on the clutch "immediately" after releasing the throttle, that is, there should be a short delay in stepping on the clutch, not at the same time. Of course, you can't step on the clutch too slowly, otherwise the car will sit backwards.
