蹦跶蹦跶小心闪到腰
[bèng da bèng da xiăo xīn shăn dào yāo]
It humorously translates to 'Bounce around carefully; you might hurt your waist.' This implies a playful caution and can be a reminder to oneself about overexertion, or metaphorically expressing carefulness while enjoying life. In other words, take things easy and do not get carried away. Enjoy your freedom but stay mindful.
