Wales are not done yet.

Substitute Elen Evans carves a path through the middle with a weaving run as Wales edge into Hong Kong's 22.

But that's a penalty for Hong Kong as Evans is then pulled for holding on.

It took longer than expected but, finally, I think Wales can breathe easy.

They have weathered a real storm from Hong Kong, who seem to be tiring after a spirited 70 minutes.

Wales will undoubtedly be disappointed with elements of their performance but, given how close they have been to losing this game, a win of any sort will come as a relief to Rowland Phillips and his players.

Wales go into the final 10 minutes with all the momentum.

They've got a line-out in the Hong Kong half and Shona Powell-Hughes makes a half-break as Wales edge towards the try-line.

One more try and they should be able to celebrate the win.

Great work from the Welsh pack who earn the penalty from the driving maul.

Elinor Snowsill, who has been showing off her kicking skills this afternoon, slots an easy one into touch as the forwards collect the line-out ball.

Jess Kavanagh-Williams is denied her hat-trick as her right boot grazes the whitewash.

But that was good play from Wales. Substitute Dyddgu Hywel with some lovely footwork deep in her own half before Kavanagh-Williams set off down the right wing and just edged into touch.

Twenty five minutes left to play in Dublin.

Jess Kavanagh-Williams looks to have finished off a great Wales team try... but was she in touch?

TMO reviewing.

Each time Wales score, you'd be tempted to think 'That's it, they'll be fine from here'.

But Hong Kong have shown they are not to be written off.

Kavanagh-Williams has her second try of the game and Wales now lead 22-15 but you sense this game is far from over.

There are some stressed looking faces among the Wales fans here in Dublin.

This was meant to be a straightforward win, even with head coach Rowland Phillips making a few changes to give some youngsters a chance.

Hong Kong, however, have other ideas. This could go down to the wire.

And they've started well in the second.

Rose Hopewell-Fong with an up-and-under kick to put Elinor Snowsill under pressure. But the fly-half gathers well before being wrapped up by Hopewell-Fong.

Hong Kong are just inches from the line...

If Wales are to push on in this second period, they'll need to gain possession.

Hong Kong had 61% in the first half, and used it well.

Elinor Snowsill gets us under way in the second half as Wales lead by seven points.

Where to start with that half?

Hong Kong secured their first ever points at a RWC through the boot of Adrienne Garvey and a try from Natasha Olson-Thorne.

Wales conceded an obscene amount of penalties, but fly-half Elinor Snowsill had her hand in two brilliant Welsh tries with a skillful finish from Jasmine Joyce thrown in the mix.

A little too close for comfort for Wales.

A closer half than I was predicting, but an enthralling one nonetheless.

Plenty to talk about at the break.

I spoke too soon. Chong Ka Yan knocks the ball on after a wild pass from Adrienne Garvey and Wales will put Hong Kong under pressure at the scrum.

Wales could do with another score before half time.

A half full of drama so far.

They might not be playing for a semi-final place but these two teams are serving up a right cracker.

Hong Kong are patiently working the ball from deep through the forwards, a slightly dangerous game but they're in control at the moment.
