The meaning of 'Shift up at 5 and down at 0' is: shift to 2nd gear above 15km/h, 3rd gear above 25km/h, 4th gear above 35km/h, and 5th gear above 45km/h; shift to 4th gear below 40km/h, 3rd gear below 30km/h, 2nd gear below 20km/h, and 1st gear below 10km/h. The details are as follows: Shifting method: The neutral position is exactly in the middle of all 6 gears. Only by finding the neutral position can you accurately locate other gears. For example, when shifting from 5th to 3rd gear, do not apply force when releasing 5th gear. Let the gear lever automatically return to the neutral position, and then push it directly upward to engage 3rd gear. If you grip the gear lever tightly with your hand, you may not accurately find the neutral position, and pushing it directly upward may result in 1st gear instead. The function of gear shifting in cars: It allows the car to drive at a very low and stable speed, which would be difficult to achieve solely relying on the engine's minimum stable RPM. The reverse gear in the transmission enables the car to move backward, while the neutral gear allows the engine to be separated from the drivetrain for extended periods during engine startup, parking, and coasting.

This rhyme is quite interesting. I remember when I was first learning manual transmission, I couldn't remember when to shift gears. My instructor taught me 'shift up at multiples of 5'—meaning when the speed reaches multiples of 5, like 15, 25, 35 km/h, quickly shift up a gear to avoid straining the engine. 'Shift down at multiples of 0' means when the speed drops to multiples of 10, like 10, 20 km/h, you should downshift to prevent the engine from struggling. Driving this way is smoother and less bumpy. I still follow this habit—it's not only fuel-efficient but also safer. Especially in city driving with frequent traffic jams, this rule is super practical for preventing the car from jerking. New drivers should really try it—it makes driving feel more effortless.

Having driven for many years, the old saying 'shift up at 5, shift down at 0' was something my instructor told me twenty years ago. Back then, cars weren't as advanced as they are now—no tachometer, just relying on experience. The engine sound would smooth out when shifting up at speeds of 15 or 25, and shifting down at speeds of 10 or 20 would prevent stalling. This simple rule helped beginners avoid mistakes. Looking back, it had to do with matching the engine's optimal 2000 RPM. Nowadays, with more electronic prompts, the rule remains a fundamental skill worth remembering in case of car malfunctions.

As a young driver of a manual transmission car, I find the rhyme 'shift up at multiples of 5' (speed in multiples of 5 for upshifting) and 'shift down at multiples of 0' (speed ending with 0 for downshifting) somewhat useful but not rigidly applicable. Modern cars perform more accurately when shifting at 2000-2500 RPM as shown on the tachometer. However, it's quite helpful for beginners to simplify decision-making, practice smooth driving, and even save some fuel while enhancing driving pleasure.

When teaching others to drive, I emphasized that the core of this mantra is matching speed and gear. For example, 'add at 5' to avoid low-speed high-gear dragging the engine, 'subtract at 0' to prevent high-speed low-gear jerking. The key is not to rush, transition slowly, and develop habits for safer driving, especially on steep slopes or in traffic to minimize mistakes.

As a car enthusiast, I find this mnemonic quite engaging: 'Shift up at 5'—change gears when the speed is a multiple of 5 to ease the engine, 'Shift down at 0'—downshift when the speed is a multiple of 10 to protect the engine. Combine this with driving fun, like downshifting before slowing down on mountain curves to enhance responsiveness. Extending this, practicing gear-shifting timing more can also prolong the vehicle's life and let you feel the charm of control.
