To me ,it was a Pintail snipe
I am just an inexperienced birder/ birdwatcher/ twitcher/ photographer with no long lens.

It is either a Pintail or Swinhoe's Snipe.  Check the tail pattern in Birds of HK and S China.
It looks like a Swinhoe's to me.

I saw it flew across and landing quietly in less than 2 sec. Only 2 photos were taken. Another photo showed the upper part of its wing.



Any additional comments?

Great that you've got this photo, well done! However, I don't think it's possible to say if it is Pintail or Swinhoes's. The two are extremely similar, and most birds have to be left as 'either/or'.

The bird has it's tail spread on the first picture. I think the outer tail feathers are probably narrow enough for pintail and too narrow for Swinhoe's, but this pair is always very difficult in the field and as Geoff says, it might be better to leave this as either/or

This is almost certainly a Swinhoe's Snipe based on the pattern of the outer tail feathers.

The following text is extracted from a detailed paper on the ifd of Pintail and Swinhoe's Snipe that Geoff and I published in the journal 'British Birds' in 2003.  If anyone would like me to email them a pdf copy of this paper please send me a private message.  I should warn you though that the paper goes to great lengths to expalin how difficult the id of the two is!!

'Although Swinhoe’s Snipe generally shows more white in the tail than Pintail Snipe, suggestions by Shirihai (1988) that this is a good field character do not take into account the variation in tail pattern of Swinhoe’s. Pintail Snipe consistently shows white tips and inner webs to the narrow outer rectrices. If present, the pale tips to the central rectrices are buffish, and rarely whitish, unlike the illustration in Hayman et al. (1986). In comparison, although Swinhoe’s Snipe usually has white tips to the outer rectrices, these may also be rich buff or pale ginger, colours rarely, if ever, shown by Pintail Snipe. The central rectrices of Swinhoe’s Snipe may also be conspicuously tipped pale, often white, unlike Pintail. Swinhoe’s Snipe consistently shows barred or chequered outer rectrices, however. On Pintail, these are typically plain, except for white tips. Patterned (barred or chequered) outer tail feathers are exceptional in Pintail, and while some Swinhoe’s occasionally show plain outer tail feathers, and thus appear extremely similar to Pintail, a bird with white tips to the central rectrices and chequered or barred outer rectrices
is most probably a Swinhoe’s Snipe.'

Thanks all of you to provide valuable opinions.

Special thanks for lpaul in sending me the paper and I will study it.
