I saw the new shoots coming out of the bottom of the tree, and impressed by the burst of energy when nature embraces the spring.I wonder if there is anything wrong with this photo technically.Are the bubbles a kind of lens flare, or some kind of fault?If they are,how did this occur, and how do I avoid them?I didn't do anything much on this photo, apart from straighening and a bit cloning.All comments, criticisms&MODs are welcome.Thank you.

The blobs are just very out of focus highlights. Tiny bright spots of natural light. Quite normal and nothing to worry about.
They are because you have got it right. A very wide aperture giving a blurred background - hence the blobs - making the main subject stand out.
A good effort and quite interesting.

Thank you Brian and Carol for your helpful advice.I couldn't remember why I didn't step closer to the tree.The photo was taken more than a month ago,vaguely remembered there was a fence,but thank you so much for telling me, very apprreciated 
Thank you Astyag and Colin for your kind comments.

As Astyag says, they're usually referred to as "Bokeh", and are perfectly normal. It's just out of focus points of light, & though I don't know the science, they take on the shape of the apperture.
Some lens manufacturers spend a lot of time, money & effort trying to give the perfect Bokeh. And some photographers do the same trying lens after lens until they find it.
Try Googling Bokeh if you want to know more, and aren't already as bored as your models.
Thank you very much Dave.I really don't know what "Bokeh" is.When Astyag mentioned "Bokeh", I tried to google it, maybe I got spelling wrong, I didn't go anywhere
,I didn't want to bother him,bucause world cup is on,so I left it.Thank you so much for telling me again.I can't keep saying that I don't know anything about technology, can I?....I have to learn a bit...I'll do what you told me.
Thanks to Astyag again.

Hi Xiaoli,
The 'bubbles' are not a lens fault it's true, but bright highlights in a picture always grab the viewers attention, so if they're not part of what you are trying to portray, or add to the setting of the shot, they are still a compositional fault that is best avoided. For that reason, I personally I don't much like them here, especially the brighter and more distracting ones in the top right corner area.
The same goes for the two yellow flashes on the top edge of the picture- bright areas actually ON the edge of the frame often lead the eye OUT of the frame.
Sorry to be blunt and tell it like it is, but I'd hate you to go down the path of ruining every picture with artefacts like these.....

Thank you very much Malc.
I did remember that I tried to clone out the top shoot, but I couldn't do it properly and not sure if I should or should not...so I decided to leave it.I only cloned out the yellow patch at the bottom part of the shoots,I didn't do it well either.My main concern was the bubbles.I understand your point and thank you for pointing it out to me.
Don't worry that I would "go down the path of ruining every picture with artefacts like these....." I'm not clever enough to be able to produce such an artefacts even if I wanted to,it was purely accidental
Thank you again for your comments and kind help all the time, my best wishes to you and take care.

It's all been said above and I agree. It's your own personal view as to whether they add to the image or hinder the overall effect. i think if there are too many or too large or in the 'wrong' place they can distract from what your trying achieve as an overall composition. I think if they are to one side of the sprouting shoots they are fine and add to the bokeh or sense of depth but when they 'overlay' that part of the pic (like the one in the middle) then they can, (in my humble opinion) distract. Overall great shot and I like the new feel you've captured in the shoots. Compo is good too. Paul
Thank you very much Paul for your kind and helpful comments.I learned a lot from this photo, from what the bubbles are to their roles suppose to be in the matter of composition.Your opinion is very much appreciated.
Thank you again and best wishes to you.
xiaoli.
