this time turn aside?

gosh ???? whata verb ??

Well,

If you turn around you show your face and cannot hide your smile, if you turn aside you turn your face away from other other person so they cannot see that you are smiling.

Hi,

I am curious that 'turn around' basically refers to turn 180-degree or 360-degree (=U-turn)? Or possible for both?

Hi Haihao

A U-turn is a 180-degree turn.
"Turn around" usually refers to some kind of 180-degree turn.

"Turn around" can (but doesn't usually) also refer to a 360-degree turn, but people would usually add things such as "all the way" or "in a circle" etc. to make this clear.

When driving:
- He turned 180 degrees. = He made a U-turn.
- He turned 360 degrees. = He did a three-sixty. (Usually a form of reckless or out-of-control driving.)

If you are on your way somewhere and then turn back, you discontinue your travel to the originally planned destination and go back to where you've come from.

If you tell someone to turn around, that typically means the person should turn their back to you or vice versa (i.e. a 180-degree turn).

PS
As regards the test sentence, if you turn your head aside (to hide a smile, for example), that would normally involve a 90-degree angle at the very most. The only time I've seen someone turn their head more than 90 degrees was in the old movie The Exorcist. As I recall, that movie had Linda Blair's head doing three-sixties.
