Dear Yong Peng,
I adapted to your previous translations. We can always add corrections and
changes.
Here is the whole part again:

117 And what, Rahula, is the wind element?
The wind element may be internal or external.
And what, Rahula, is the internal wind element?
That, internally, and individually, is wind, windy, and clung to.
such as winds going upwards, winds going downwards, winds in the belly,
winds in the abdomen, winds going across the limbs, inbreathing,
outbreathing
or whatever else internally, and individually, is motion, wind, is clung to,
this is called, rahula, the internal element of motion.
But that very internal motion element and that external motion element
are simply motion element.
Thus, "this is not mine, this I am not, this is not myself" has to be seen
with right wisdom just as it is.
Having seen this with right wisdom just as it is, the mind is detached from
and becomes dispassionate towards the motion element."

(Note: vaayo,wind or motion, has the
characteristic of motion or pressure.)
Nina.
