I suddenly bumped into him in the corridor.

一头扑进水里

dive headfirst into the water

一头倒在床上

fall headfirst onto the bed

You can rush headfirst into professional work.

一头尖的棍子

a stick with one sharp end

坐在桌子另一头

sit at the other end of the table

他比你高出一头。

He is a head taller than you.

The advantage is with our side.

坐在一头

sit together
