Winking Girl

• Asia
In China and reportedly to some extent in India, winking may be seen as an offensive gesture.
However, winking in the Indian subcontinent often has similar connotations as in the West. It can be used to signal an "inside" joke, a sly gesture shared between two people privately, unbeknownst to those around them, as in a social gathering. It can also be a naughty "come on" by a girl to a boy or vice versa.
When Frederick Spencer Chapman was training Chinese guerillas in Malaya to shoot rifles, he found that a large proportion of them were unable to close only one eye at a time.
