Two chinese boys traveled 80km bus undercarriage

I think there may be some confusion here!

It's highly unlikely that two Chinese boys traveled 80km under a bus. In fact, it's not physically possible for humans to travel such a long distance under a bus, as the space is too small and there are many obstacles that would prevent them from moving safely.

Additionally, it's important to note that traveling under a bus is extremely dangerous and could result in serious injury or even death.

Could you please provide more context or clarify what you mean by this statement? I'm here to help and provide assistance if needed!
