As for the frustrations of Eado 16 models, please let the masters who know about it come in and talk about it.

I don’t know when the frustration you mentioned occurred. Generally, when shifting gears at low speeds, it can be solved by depressing the clutch and throwing down the accelerator to shift gears. When lifting the clutch, be sure to apply it at an even speed and softly, and avoid releasing the clutch pedal suddenly. When you are a veteran, lift the clutch pedal to the semi-linked position first, pause for a while, and then release the clutch with your right foot.
