"Measuring the world with wheels and measuring life with steps" is a metaphor. "Measuring the world with wheels" means exploring every corner of the world by driving or riding. This kind of travel can make people know more about different cultures, landscapes and lifestyles, broaden their horizons and increase their knowledge.
"Measuring life with footsteps" emphasizes shaping life through personal experiences and actions. This means actively participating in various activities, stepping out of your comfort zone, trying new things and constantly challenging yourself, thus enriching your life experience and realizing personal growth.
